465125c5e7 Added support for 32-bit clock ticks: when reading the 32-bit value, make sure that it does not change between readouts to avoid reading right in the middle of it being updated 2010-02-23 18:41:20 +00:00

a4df6e0fbf Remove the read from TAIV - this should not be done for TIMERA0 interrupts (in fact, doing so messes up the other timer a interrupts, like the clock tick...) 2009-12-08 23:39:45 +00:00

b90075ea0a bug fix, msp430 hw bug (undocumented):
when in continuous/compare mode the interrupt handler may get called before CCR==TR.

behavior observed when the timer is toggled between STOP/CONT in an external interrupt handler (serial input).

possibly this problem may also affect watchdog timer/timer B

fc6d059d24 Added a clock_seconds() function prototype to core/sys/clock.h, that returns seconds in 32 bit format. On platforms like the MSP430, which has a 16 bit native datatype, this cannot be implemented with an interrupt tick that increments a 32 bit value because access is not atomic. Instead, the MSP430 code increments 16 bit seconds value and converts this into a 32 bit value through an offset calculation. If the new value is smaller than the last check, the offset is incremented by 65536. This change also means that CLOCK_CONF_SECOND must be a power of two because a modulo operation is used inside the periodic tick interrupt handler. 2008-07-07 23:38:09 +00:00
