6.2 Port A
Port A shares functions with the timer system and has:
DDRA7 — Data Direction for Port A Bit 7
PAEN — Pulse Accumulator System Enable Bit
PAMOD — Pulse Accumulator Mode Bit
PEDGE — Pulse Accumulator Edge Control Bit
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

Parallel Input/Output (I/O) Ports
Overridden if an output compare function is configured to control the PA7 pin
The pulse accumulator uses port A bit 7 as the PAI input, but the pin can also be used as
general-purpose I/O or as an output compare.
