Port B Data Direction Register (PBDDR)
PBDDR is an 8-bit write-only register that can select input or output for each pin in port B. When
pins are used for TPC output, the corresponding PBDDR bits must also be set.
Bit
Initial value
Read/Write
A pin in port B becomes an output pin if the corresponding PBDDR bit is set to 1, and an input pin
if this bit is cleared to 0.
PBDDR is a write-only register. Its value cannot be read. All bits return 1 when read.
PBDDR is initialized to H'00 by a reset and in hardware standby mode. In software standby mode
it retains its previous setting. If a PBDDR bit is set to 1, the corresponding pin maintains its output
state in software standby mode.
