|
||
|
|
* |[1] |RSTEN |WDT Time-out Reset Enable Bit (Write Protect)
|
||
|
|
* | | |Setting this bit will enable the WDT time-out reset function If the WDT up counter value has not been cleared after the specific WDT reset delay period expires.
|
||
|
|
* | | |0 = WDT time-out reset function Disabled.
|
||
|
|
* | | |1 = WDT time-out reset function Enabled.
|
||
|
|
* | | |Note: This bit is write protected. Refer to the SYS_REGLCTL register.
|
||
|
|
* |[2] |RSTF |WDT Time-out Reset Flag
|
||
|
|
* | | |This bit indicates the system has been reset by WDT time-out reset or not.
|
||
|
|
* | | |0 = WDT time-out reset did not occur.
|
||
|
|
* | | |1 = WDT time-out reset occurred.
|
||
|
|
* | | |Note: This bit is cleared by writing 1 to it.
|
||
|
|
* |[3] |IF |WDT Time-out Interrupt Flag
|
||
|
|
* | | |This bit will set to 1 while WDT up counter value reaches the selected WDT time-out interval
|
||
|
|
* | | |0 = WDT time-out interrupt did not occur.
|
||
|
|
* | | |1 = WDT time-out interrupt occurred.

||
|
|
* | | |Note: This bit is cleared by writing 1 to it.
|
||
|
|
* |[4] |WKEN |WDT Time-out Wake-up Function Control (Write Protect)
|
||
|
|
* | | |If this bit is set to 1, while WDT time-out interrupt flag IF (WDT_CTL[3]) is generated to 1 and interrupt enable bit INTEN (WDT_CTL[6]) is enabled, the WDT time-out interrupt signal will generate a wake-up trigger event to chip.
|
||
|
|
* | | |0 = Wake-up trigger event Disabled if WDT time-out interrupt signal generated.
|
||
|
|
* | | |1 = Wake-up trigger event Enabled if WDT time-out interrupt signal generated.
|
||
|
|
* | | |Note1: This bit is write protected. Refer to the SYS_REGLCTL register.
|
||
|
|
* | | |Note2: Chip can be woken up by WDT time-out interrupt signal generated only if WDT clock source is selected to 10 kHz internal low speed RC oscillator (LIRC) or LXT.
|
||
|
|
* |[5] |WKF |WDT Time-out Wake-up Flag (Write Protect)
|
||
|
|
* | | |This bit indicates the interrupt wake-up flag status of WDT
|
||
|
|
* | | |0 = WDT does not cause chip wake-up.
|
||
|
|
* | | |1 = Chip wake-up from Idle or Power-down mode if WDT time-out interrupt signal generated.
|
||
|
|
* | | |Note1: This bit is write protected. Refer to the SYS_REGLCTL register.
|
||
|
|
* | | |Note2: This bit is cleared by writing 1 to it.
|
||
|
|
* |[6] |INTEN |WDT Time-out Interrupt Enable Bit (Write Protect)
|
||
|
|
* | | |If this bit is enabled, the WDT time-out interrupt signal is generated and inform to CPU.
|
||
|
|
* | | |0 = WDT time-out interrupt Disabled.
|
||
|
|
* | | |1 = WDT time-out interrupt Enabled.
|
||
|
|
* | | |Note: This bit is write protected. Refer to the SYS_REGLCTL register.
|
||
|
|
* |[7] |WDTEN |WDT Enable Bit (Write Protect)
|
||
|
|
* | | |0 = WDT Disabled (This action will reset the internal up counter value).
|
||
|
|
* | | |1 = WDT Enabled.
|
||
|
|
* | | |Note1: This bit is write protected. Refer to the SYS_REGLCTL register.
|
||
|
|
* | | |Note2: If CWDTEN[2:0] (combined by Config0[31] and Config0[4:3]) bits is not configured to 111, this bit is forced as 1 and user cannot change this bit to 0.
|
||
|
|
* |[11:8] |TOUTSEL |WDT Time-out Interval Selection (Write Protect)
|
||
|
|
* | | |These four bits select the time-out interval period for the WDT.
|
||
|
|
* | | |0000 = 2^4 * WDT_CLK.
|
||
|
|
* | | |0001 = 2^6 * WDT_CLK.
|
||
|
|
* | | |0010 = 2^8 * WDT_CLK.
|
||
|
|
* | | |0011 = 2^10 * WDT_CLK.
|
||
|
|
* | | |0100 = 2^12 * WDT_CLK.
|
||
|
|
* | | |0101 = 2^14 * WDT_CLK.
|
||
|
|
* | | |0110 = 2^16 * WDT_CLK.
|
||
|
|
* | | |0111 = 2^18 * WDT_CLK.
|
||
|
|
* | | |1000 = 2^20 * WDT_CLK.
|
||
|
|
* | | |Note: This bit is write protected. Refer to the SYS_REGLCTL register.
|
||
|
|
* |[30] |SYNC |WDT Enable Control SYNC Flag Indicator (Read Only)
|
||
|
|
* | | |If user executes enable/disable WDTEN (WDT_CTL[7]), this flag can be indicated enable/disable WDTEN function is completed or not.
|
||
|
|
* | | |0 = Set WDTEN bit is completed.
|
||
|
|
* | | |1 = Set WDTEN bit is synchronizing and not become active yet.
|
||
|
|
* | | |Note: Performing enable or disable WDTEN bit needs 2 * WDT_CLK period to become active.
|
||
|
|
* |[31] |ICEDEBUG |ICE Debug Mode Acknowledge Disable Bit (Write Protect)
|
||
|
|
* | | |0 = ICE debug mode acknowledgement affects WDT counting.
|
||
|
|
* | | |WDT up counter will be held while CPU is held by ICE.
|
||
|
|
* | | |1 = ICE debug mode acknowledgement Disabled.
|
||
|
|
* | | |WDT up counter will keep going no matter CPU is held by ICE or not.

* | | |When WDT time-out happened, user has a time named WDT Reset Delay Period to clear WDT counter by writing 0x00005aa5 to RSTCNT (WDT_RSTCNT[31:0]) to prevent WDT time-out reset happened.
|
||
|
|
* | | |User can select a suitable setting of RSTDSEL for different WDT Reset Delay Period.
|
||
|
|
* | | |00 = WDT Reset Delay Period is 1026 * WDT_CLK.
