Port 9 Data Register (P9DR)
P9DR is an 8-bit readable/writable register that stores output data for pins P9
in P9DDR is set to 1, if port 9 is read the value of the corresponding P9DR bit is returned. When a
bit in P9DDR is cleared to 0, if port 9 is read the corresponding pin level is read.

Initial value
Read/Write
Bits 7 and 6 are reserved. They cannot be modified and are always read as 1.
P9DR is initialized to H'C0 by a reset and in hardware standby mode. In software standby mode it
retains its previous setting.
