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

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.
• After power-on reset
• When recovering from Stop state
