TOF — Timer Overflow Interrupt Flag
Refer to 7.2 Main Timer.
RTIF — Real-Time Interrupt Flag
Refer to 7.3 Real-Time Interrupt.
PAOVF — Pulse Accumulator Overflow Interrupt Flag
If the PAOVI enable bit is set when the pulse accumulator counter register (PCNT) rolls over to $0000,
this flag is set and an interrupt is generated.
0 = PCNT has not rolled over since either the PAOVF flag bit was last cleared or when the PAOVI
enable bit was set.
1 = PCNT has rolled over to $0000
PAIF — Pulse Accumulator Input Edge Interrupt Flag
If the PAII enable bit is set when an edge is detected on the pulse accumulator input pin (PA7/PAI), this
flag is set and an interrupt is generated.
0 = No edge has been detected on the PAI pin
1 = An edge (rising or falling, depending on configuration) has been detected on the PAI pin
Bits [3:0] — Not Implemented
Always read zero
