9.5
Port B is an 8-bit I/O port that also has other functions. Port B has the following registers. For
details on register addresses and register states during each processing, refer to appendix A, On-
Chip I/O Register.
• Port B data direction register (PBDDR)
• Port B data register (PBDR)
• Port B register (PORTB)
• Port B pull-up MOS control register (PBPCR)
• Port B open-drain control register (PBODR)
9.5.1
PBDDR is an 8-bit write-only register, the individual bits of which specify whether the pins of
port B are used for input or output.
PBDDR cannot be read; if it is, an undefined value will be read.

Description
When a pin is specified as a general purpose I/O
port, setting this bit to 1 makes the corresponding
port 1 pin an output pin. Clearing this bit to 0 makes
the pin an input pin.
