Port B Data Direction Register (PBDDR)
PBDDR is an 8-bit write-only register, the individual bits of which specify input or output for the
pins of port B. PBDDR cannot be read; if it is, an undefined value will be read.
PBDDR is initialized to H'00 by a reset, and in hardware standby mode. It retains its prior state in
software standby mode. The OPE bit in SBYCR is used to select whether the address output pins
retain their output state or become high-impedance when a transition is made to software standby
mode.
• Modes 4 and 5
• Mode 6
• Mode 7
Bit
Initial value :
R/W
The corresponding port B pins are address outputs irrespective of the value of the PBDDR bits.
Setting a PBDDR bit to 1 makes the corresponding port B pin an address output, while
clearing the bit to 0 makes the pin an input port.
Setting a PBDDR bit to 1 makes the corresponding port B pin an output port, while clearing
the bit to 0 makes the pin an input port.
