Port 4 data direction register
Port 4 data register
Port 4 Data Direction Register (P4DDR)
P4DDR is an 8-bit readable/writable register that controls the input/output direction of each pin in
port 4. A pin functions as an output pin if the corresponding P4DDR bit is set to 1, and as an input
pin if this bit is cleared to 0.
P4DDR is a write-only register. Read data is invalid. If read, all bits always read 1.
P4DDR 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 P4DDR bit
is set to 1, the corresponding pin remains in the output state.
If a transition to software standby mode occurs while port 4 is being used by an on-chip
supporting module (for example, for 8-bit timer output), the on-chip supporting module will be
initialized, so the pin will revert to general-purpose input/output, controlled by P4DDR and P4DR.
