ATmega32/64/M1/C1

14.16.10 PSC Interrupt Mask Register – PIM

• Bit 7:4 – not use

not use.

• Bit 3 – PEVE2 : PSC External Event 2 Interrupt Enable

When this bit is set, an external event which can generates a a fault on module 2 generates also

an interrupt.

• Bit 2 – PEVE1 : PSC External Event 1 Interrupt Enable

When this bit is set, an external event which can generates a fault on module 1 generates also

an interrupt.

• Bit 1 – PEVE0 : PSC External Event 0 Interrupt Enable

When this bit is set, an external event which can generates a fault on module 0 generates also

an interrupt.

• Bit 0 – PEOPE : PSC End Of Cycle Interrupt Enable

When this bit is set, an interrupt is generated when PSC reaches the end of the whole cycle.

14.16.11 PSC Interrupt Flag Register – PIFR

• Bit 7:4 – not use

not use.

• Bit 3 – PEV2 : PSC External Event 2 Interrupt

This bit is set by hardware when an external event which can generates a fault on module 2

occurs.

Must be cleared by software by writing a one to its location.

This bit can be read even if the corresponding interrupt is not enabled (PEVE2 bit = 0).
