NOTE:
Alternate function:
DDRA7 — Data Direction for Port A Bit 7
Even when port A bit 7 is configured as an output, the pin still drives the input to
the pulse accumulator.
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
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.

This bit is overridden if an output compare function is configured to control the
PA3 pin.
