Name
Port B data direction register
Port B output data register
Port B input data register
Note: The port B data direction register (PBDDR) and port 7 input data register 7 (P7PIN) have
Port B Data Direction Register (PBDDR)
PBDDR is an 8-bit register that controls the input/output direction of each pin in port B. A pin
functions as an output pin if the corresponding PBDDR bit is set to 1, and as an input pin if this bit
is cleared to 0.
PBDDR is a write-only register. Read data is invalid. If read, the values of the port 7 data input
register (P7PIN) are returned, indicating the pin levels of port 7.
PBDDR is initialized to H'00 by a reset and in hardware standby mode. In software standby mode
it retains its existing values, so if a transition to software standby mode occurs while a PBDDR bit
is set to 1, the corresponding pin remains in the output state.
