868 / 1228 page  Section 19 Pin Function Controller (PFC) Rev. 2.00 May. 08, 2008 Page 844 of 1200 REJ09B0344-0200 19.1.5 Port D I/O Register (PDIOR) PDIOR is a 16-bit readable/writable register that is used to set the pins on port D as inputs or outputs. Bits PD15IOR to PD0IOR correspond to pins PD15 to PD0. PDIOR is enabled when the port D pins are functioning as general-purpose inputs/outputs (PD15 to PD0). In other states, PDIOR is disabled. A given pin on port D will be an output pin if the corresponding bit in PDIOR is set to 1, and an input pin if the bit is cleared to 0. PDIOR is initialized to H'0000 by a power-on; but is not initialized by a manual reset or in sleep mode or software standby mode. 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 0000000000000000 R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W Bit: Initial value: R/W: PD13 IOR PD12 IOR PD11 IOR PD9 IOR PD8 IOR PD7 IOR PD6 IOR PD5 IOR PD4 IOR PD3 IOR PD2 IOR PD1 IOR PD0 IOR PD15 IOR PD14 IOR PD10 IOR 19.1.6 Port D Control Registers L1 to L4 (PDCRL1 to PDCRL4) PDCRL1 to PDCRL4 are 16-bit readable/writable registers that are used to select the functions of the multiplexed pins on port D. PDCRL1 to PDCRL4 are initialized to the values shown in table 19.6 by a power-on reset; but are not initialized by a manual reset or in sleep mode or software standby mode.
