431 / 1071 page  Section 10 I/O Ports Rev. 5.00 Aug 08, 2006 page 345 of 982 REJ09B0054-0500 10.9.4 Port D Pull-Up MOS Control Register (PDPCR) PDPCR controls the on/off state of port D input pull-up MOS. Bit Bit Name Initial Value R/W Description 7 PD7PCR 0 R/W 6 PD6PCR 0 R/W 5 PD5PCR 0 R/W 4 PD4PCR 0 R/W 3 PD3PCR 0 R/W 2 PD2PCR 0 R/W 1 PD1PCR 0 R/W 0 PD0PCR 0 R/W When a pin is specified as an input port, setting the corresponding bit to 1 turns on the input pull-up MOS for that pin. 10.9.5 Pin Functions Port D pins also function as data I/O pins. The values of register and pin functions are shown below. • PD7/D15, PD6/D14, PD5/D13, PD4/D12, PD3/D11, PD2/D10, PD1/D9, PD0/D8 The pin functions are switched as shown below according to the combination of the operating mode and the PDnDDR bit. Operating mode Modes 4 to 6 Mode 7 PDnDDR 01 Pin functions Data I/O pin PDn input pin PDn output pin Note: n = 7 to 0 |
