14.16.10 PSC Interrupt Mask Register – PIM
14.16.11 PSC Interrupt Flag Register – PIFR
7647A–AVR–02/08
Bit
Read/Write
Initial Value
• 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.
Bit
Read/Write
Initial Value
• 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).
