Section 15 Pin Function Controller (PFC)
15.3.2
PACR1 and PACR2 are 16-bit read/write registers that select the functions of the sixteen
multiplexed pins of port A. PACR1 selects the function of the upper eight bits of port A; PACR2
selects the function of the lower eight bits of port A. PACR1 and PACR2 are initialized to H'3302
and H'FF95 respectively by a power-on reset but are not initialized by a manual reset, or in
standby mode or sleep mode.
PACR1:
Bits 15 and 14—PA15 Mode (PA15MD1 and PA15MD0): PA15MD1 and PA15MD0 select the
function of the PA15/IRQ3/DREQ1 pin.
