DDRA3 — Data Direction for Port A Bit 3
I4/O5 — Input Capture 4/Output Compare 5 Bit
RTR[1:0] — RTI Interrupt Rate Select Bits
This 8-bit read/write register contains the count of external input events at the PAI
input or the accumulated count. The PACNT is readable even if PAI is not active in
gated time accumulation mode. The counter is not affected by reset and can be
read or written at any time. Counting is synchronized to the internal PH2 clock so
that incrementing and reading occur during opposite half cycles.
The pulse accumulator control bits, PAOVI and PAII, PAOVF and PAIF, are located
within timer registers TMSK2 and TFLG2.
