NOTE:
Address:
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

Figure 6-2. Pulse Accumulator Control Register (PACTL)
Write:
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.
