Note 1:
INTF flag is sampled here (every Q1).
2:
Asynchronous interrupt latency = 3-5 T
CY
. Synchronous latency = 3-4 T
CY
, where T
CY
= instruction cycle time.
Latency is the same whether Inst (PC) is a single cycle or a 2-cycle instruction.
3:
For minimum width of INT pulse, refer to AC specifications in
.
4:
INTF is enabled to be set any time during the Q4-Q1 cycles.
