Section 7 I/O Ports
Port 9 Data Register (P9DR): P9DR is an 8-bit readable/writable register that stores output data
for port 9. When port 9 functions as an output port, the value of this register is output. When a bit
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 logic level is read.
Bits 7 and 6 are reserved. They are fixed at 1, and cannot be modified.
P9DR is initialized to H'C0 by a reset and in hardware standby mode. In software standby mode it
retains its previous setting.
