Contiki v1.3:
|
|
. I still see 2 cases of abnormal operation. These occur during boot up, during some period of disk access.
|
|
. See Contiki's IRQ() in apple2-stdmou.s
|
|
|
|
** Normal operation **
|
|
|
|
<VBL EVENT> : h/w asserts IRQ
|
|
<6502 jumps to IRQ vector>
|
|
. MOUSE_SERVE : h/w deasserts IRQ
|
|
. MOUSE_READ
|
|
. RTS with C=1
|
|
|
|
<VBL EVENT> : h/w asserts IRQ
|
|
<6502 jumps to IRQ vector>
|
|
. MOUSE_SERVE : h/w deasserts IRQ
|
|
. MOUSE_READ
|
|
. RTS with C=1
|
|
|
|
Etc.
|
|
|
|
** Abnormal operation **
|
|
|
|
<VBL EVENT> : h/w asserts IRQ
|
|
<6502 jumps to IRQ vector>
|
|
. MOUSE_SERVE (for VBL EVENT) : h/w deasserts IRQ
|
|
<VBL EVENT> : h/w asserts IRQ
|
|
. MOUSE_READ
|
|
- this clears the mouse IRQ status byte in the mouse-card's "h/w"
|
|
. RTS with C=1
|
|
|
|
<6502 jumps to IRQ vector>
|
|
. MOUSE_SERVE (for MOVEMENT EVENT) : h/w deasserts IRQ
|
|
- but IRQ status byte is 0
|
|
. RTS with C=0
