Freescale Semiconductor
Edge-sensitive Interrupt Request Width
IRQA, IRQB Assertion to External Data Memory
Access Out Valid, caused by first instruction execution
in the interrupt service routine
IRQA, IRQB Assertion to General Purpose Output
Valid, caused by first instruction execution in the
interrupt service routine
IRQA Low to First Valid Interrupt Vector Address Out
recovery from Wait State
IRQA Width Assertion to Recover from Stop State
Delay from IRQA Assertion to Fetch of first instruction
(exiting Stop)
OMR Bit 6 = 0
OMR Bit 6 = 1
Duration for Level Sensitive IRQA Assertion to Cause
the Fetch of First IRQA Interrupt Instruction (exiting
Stop)
OMR Bit 6 = 0
OMR Bit 6 = 1
Delay from Level Sensitive IRQA Assertion to First
Interrupt Vector Address Out Valid (exiting Stop)
OMR Bit 6 = 0
OMR Bit 6 = 1
1. In the formulas, T = clock cycle. For an operating frequency of 80MHz, T = 12.5ns.
2. Circuit stabilization delay is required during reset when using an external clock or crystal oscillator in two cases:
3. The minimum is specified for the duration of an edge-sensitive IRQA interrupt required to recover from the Stop state. This is
not the minimum required so that the IRQA interrupt is accepted.
4. The interrupt instruction fetch is visible on the pins only in Mode 3.
5. Parameters listed are guaranteed by design.
