PCCR is a 16-bit read/write register that selects the functions for the sixteen port C multiplexed
pins. There are instances when these register settings will be ignored, depending on the operation
mode. Refer to table 16.3, Pin Arrangement by Mode, for details.
PCCR is initialized to H'0000 by power-on resets but is not initialized for reset by WDT, standby
mode, or sleep mode, so the previous data is maintained.
The settings in this register are functional only in the SH7016 and SH7017. In the SH7014, there
are no pins corresponding to this register, and it should not be read or written to.
Bit 15⎯PC15 Mode (PC15MD): Selects the function of the PC15/A15 pin.
