Section 10 I/O Ports
10.10
Port B is an 8-bit I/O port that also has other functions. Port B has the following registers.
• 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)
10.10.1 Port B Data Direction Register (PBDDR)
The individual bits of PBDDR specify input or output for the pins of port B. PBDDR cannot be
read; if it is, an undefined value will be read.

Modes 1 and 2
Port B pins are address outputs regardless of
the PBDDR settings.
Modes 7 (when EXPE = 1) and 4
Setting a PBDDR bit to 1 makes the
corresponding pin an address output, while
clearing a PBDDR bit to 0 makes the
corresponding pin an input port.
Mode 7 (when EXPE = 0)
Port B is an I/O port, and its pin functions can be
switched with PBDDR.
