P9DR stores output data for the port 9 pins that are
used as the general output port.
If this register is read, the P9DR values are read for
the bits with the corresponding P9DDR bits set to 1.
For the bits with the corresponding P9DDR bits
cleared to 0, the pin states are read.

Pin Functions
The relationship between register setting values and pin functions are as follows.
•
P97/
WAIT
/
CS256
The pin function is switched as shown below according to the operating mode and the
combination of the CS256E bit in SYSCR, the WMS1 bit in WSCR, the WMS21 bit in
WSCR2, and the P97DDR bit.
