Table 2-7 Reset, Stop, Mode Select, and Interrupt Timing (60 MHz) (Continued)
Delay from External Data Memory Address Output Valid
Caused by First Interrupt Instruction Execution to
Interrupt Request Deassertion for Level Sensitive Fast
Interrupts
Delay from General-Purpose Output Valid Caused by the
Execution of the First Interrupt Instruction to IRQA,
IRQB, IRQC Deassertion for Level Sensitive Fast
Interrupts—If 2nd Interrupt Instruction is:
Synchronous setup time from IRQA, IRQB, IRQC
assertion to Synchronous falling edge of CLKO
Falling Edge of CLKO to First Interrupt Vector Address
Out Valid after Synchronous recovery from Wait State
IRQA Width Assertion to Recover from STOP State
Delay from IRQA Assertion to Fetch of first instruction
(exiting STOP)
Duration for Level Sensitive IRQA Assertion to Cause the
Fetch of First IRQA Interrupt Instruction (exiting
STOP)
Delay from Level Sensitive IRQA Assertion to First
Interrupt Vector Address Out Valid (exiting STOP)
DR Asserted to CLK low (Setup Time for Synchronous
Recovery from Wait State)
CLK low to DSO (ACK) Valid (Enter Debug Mode) After
Synchronous Recovery from Wait State
DR to DSO (ACK) Valid (Enter Debug Mode)
