14.3.2
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 top eight bits of port A; PACR2
selects the function of the bottom eight bits of port A. PACR1 and PACR2 are initialized to
H'3302 and H'FF95 respectively by power-on resets but are not initialized for manual resets,
standby mode, or sleep mode.
PACR1:
• Bits 15 and 14 (PA15 mode (PA15MD1 and PA15MD0)): PA15MD1 and PA15MD0 select
RENESAS 402
the function of the PA15/IRQ3/DREQ1 pin.
