Pulse Accumulator Edge Control — This bit is active only when the Pulse Accumulator A is enabled
(PAEN = 1). Refer to
For PAMOD bit = 0 (event counter mode).
0 Falling edges on IC7 pin cause the count to be incremented
1 Rising edges on IC7 pin cause the count to be incremented
For PAMOD bit = 1 (gated time accumulation mode).
0 IC7 input pin high enables bus clock divided by 64 to Pulse Accumulator and the trailing falling edge on IC7
1 IC7 input pin low enables bus clock divided by 64 to Pulse Accumulator and the trailing rising edge on IC7 sets
If the timer is not active (TEN = 0 in TSCR1), there is no divide-by-64 since the ÷64 clock is generated by the
timer prescaler.
Clock Select Bits — For the description of PACLK please refer to
If the pulse accumulator is disabled (PAEN = 0), the prescaler clock from the timer is always used as an input
clock to the timer counter. The change from one selected clock to the other happens immediately after these bits
are written. Refer to
Pulse Accumulator A Overflow Interrupt Enable
0 Interrupt inhibited
1 Interrupt requested if PAOVF is set
Pulse Accumulator Input Interrupt Enable
