Note:
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.
Bits 7 and 6 are reserved. They cannot be modified and always read as 1.
Bit
Initial value
Read/Write
When 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. When transition is made to software standby mode while a P9DDR
bit is set to 1, the corresponding pin maintains its output state.
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 level is read.
