Port 8 Data Direction Register (P8DDR)
P8DDR is an 8-bit readable/writable register that controls the input/output direction of each pin in
port 8. A pin functions as an output pin if the corresponding P8DDR bit is set to 1, and as an input
pin if this bit is cleared to 0. P8DDR is a write-only register. Read data is invalid. If read, all bits
always read 1. Bit 7 is a reserved bit that always reads 1.
P8DDR is initialized to H'80 by a reset and in hardware standby mode. In software standby mode
P8DDR retains its existing values, so if a transition to software standby mode occurs while a
P8DDR bit is set to 1, the corresponding pin remains in the output state.
Port 8 Data Register (P8DR)
P8DR is an 8-bit register that stores data for pins P8
reads 1.
When a P8DDR bit is set to 1, if port 8 is read, the value in P8DR is obtained directly, regardless
of the actual pin state. When a P8DDR bit is cleared to 0, if port 8 is read the pin state is obtained.
This also applies to pins used by on-chip supporting modules.
P8DR is initialized to H'80 by a reset and in hardware standby mode. In software standby mode it
retains its existing values.
