Delay from General-Purpose
Output Valid Caused by the
Execution of the First Inter-
rupt Instruction to IRQA,
IRQB Deassertion for Level
Sensitive Fast Interrupts — If
2nd Interrupt Instruction is:
(See Note 2)
Synchronous setup time from
IRQA, IRQB assertion to
Synchronous falling edge of
CLKO (See Notes 5 and 6)
Falling Edge of CLKO to First
Interrupt Vector Address Out
Valid after Synchronous
recovery from Wait State
(See Notes 3 and 5)
IRQA Width Assertion to
Recover from Stop State
(See Note 4)
Delay from IRQA Assertion to
Fetch of first instruction (exit-
ing Stop)
(See Notes 1 and 3)
Duration for Level Sensitive
IRQA Assertion to Cause the
Fetch of First IRQA Interrupt
Instruction (exiting Stop)
(See Notes 1 and 3)
Delay from Level Sensitive
IRQA Assertion to First Inter-
rupt Vector Address Out
Valid (exiting Stop)
(See Notes 1 and 3)
