Section 9 I/O Ports
Mode 7 (Single-Chip Mode): Port 8 is a generic input/output port. A pin in port 8 becomes an
output port if the corresponding P8DDR bit is set to 1, and an input port if this bit is cleared to 0.
P8DDR is a write-only register. Its value cannot be read. All bits return 1 when read.
P8DDR is initialized to H'F0 in modes 1 to 4 and H'E0 in modes 5 to 7 by a reset and in hardware
standby mode. In software standby mode it retains its previous setting, so if a P8DDR bit is set to
1 while port 8 acts as an I/O port, the corresponding pin maintains its output state in software
standby mode.
Port 8 Data Register (P8DR)
P8DR is an 8-bit readable/writable register that stores output data for pins P8
acts as an output port, the value of this register is output. When a bit in P8DDR is set to 1, if port 8
is read the value of the corresponding P8DR bit is returned. When a bit in P8DDR is cleared to 0,
if port 8 is read the corresponding pin level is read.
Bits 7 to 5 are reserved. They cannot be modified and always are read as 1.
P8DR is initialized to H'E0 by a reset and in hardware standby mode. In software standby mode it
retains its previous setting.
