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
