Port 9 Data Direction Register (P9DDR)
P9DDR is an 8-bit write-only register that can select input or output for each pin in port 9.
Bit
Initial value
Read/Write
A pin in port 9 becomes an output port if the corresponding P9DDR bit is set to 1, and an input
port if this bit is cleared to 0.
P9DDR is a write-only register. Its value cannot be read. All bits return 1 when read.
P9DDR is initialized to H'C0 by a reset and in hardware standby mode. In software standby mode
it retains its previous setting. If a P9DDR bit is set to 1, the corresponding pin maintains its output
state in software standby mode.
