Description
P9DR stores output data for the port 9 pins that are
used as the general output port except for bit 6.
If a port 9 read is performed while the P9DDR bits
are set to 1, the P9DR values are read. If a port 9
read is performed while the P9DDR bits are cleared
to 0, the pin states are read.
Description
Reserved
The initial value should not be changed.
When the pins are in input state, the corresponding
input pull-up MOS is turned on when a P9PCR bit
is set to 1.
