Section 9 I/O Ports
Port D MOS Pull-Up Control Register (PDPCR)
PDPCR is an 8-bit readable/writable register that controls the MOS input pull-up function
incorporated into port D on an individual bit basis.
When a PDDDR bit is cleared to 0 (input port setting) in mode 7, setting the corresponding
PDPCR bit to 1 turns on the MOS input pull-up for the corresponding pin.
PDPCR is initialized to H'00 by a reset, and in hardware standby mode. It retains its prior state in
software standby mode.
9.8.3
In modes 4 to 6, port D pins automatically function as data bus input/output pins (D15 to D8). In
mode 7, each pin in port D functions as an input/output port, and input or output can be specified
individually for each pin. Port D pin functions are shown in table 9.16.
