Name: Generic Clock (compatible) | ||
ID: 0x12d0b402 | ||
Version: 1 | ||
|
||
Interrupts do different things depending on contents of the A register: | ||
|
||
A | BEHAVIOR | ||
---+---------------------------------------------------------------------------- | ||
0 | The B register is read, and the clock will tick 60/B times per second. | ||
| If B is 0, the clock is turned off. | ||
1 | Store number of ticks elapsed since last call to 0 in C register | ||
2 | If register B is non-zero, turn on interrupts with message B. If B is zero, | ||
| disable interrupts | ||
---+---------------------------------------------------------------------------- | ||
|
||
When interrupts are enabled, the clock will trigger an interrupt whenever it | ||
ticks. | ||
