14.3.1
The port A I/O register (PAIOR) is a 16-bit read/write register that selects input or output for
individual pins on a bit-by-bit basis. Bits PA15IOR–PA0IOR correspond to pins
PA15/IRQ3/DREQ1–PA0/CS4/TIOCA0. PAIOR is enabled when the port A pins function as
input/outputs (PA15–PA0) and for ITU input capture and output compare (TIOCA1, TIOCA0,
TIOCB1, and TIOCB0). For other functions, they are disabled. For port A pin functions PA15–
PA0 and TIOCA1, TIOCA0, TIOCB1, and TIOCB0, a given pin in port A is an output pin if its
corresponding PAIOR bit is set to 1, and an input pin if the bit is cleared to 0.
PAIOR is initialized to H'0000 by power-on resets; however, it is not initialized for manual resets,
standby mode, or sleep mode.
