Pin Function Controller (PFC) Rev.5.00 Sep. 27, 2007 Page 459 of 716 REJ09B0398-0500 16.3.6 Port C Control Register (PCCR) ⎯ SH7016, SH7017 ⎯ Bit: 15 14 13 12 11 10 9 8 PC15 MD PC14 MD PC13 MD PC12 MD PC11 MD PC10 MD PC9 MD PC8 MD Initial value: 0 0 0 0 0 0 0 0 R/W: R/W R/W R/W R/W R/W R/W R/W R/W Bit: 7 6 5 4 3 2 1 0 PC7 MD PC6 MD PC5 MD PC4 MD PC3 MD PC2 MD PC1 MD PC0 MD Initial value: 0 0 0 0 0 0 0 0 R/W: R/W R/W R/W R/W R/W R/W R/W R/W 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. Bit 15 PC15MD Description 0 General input/output (PC15) (initial value) (A15 in on-chip ROM invalid mode) 1 Address output (A15) (PC15 in single chip mode) |
