Port C pins are general-purpose I/O (PC[7:0]) in single-chip mode. In expanded mul-
tiplexed mode, port C pins are configured as multiplexed address/data pins. During the
data cycle, bits [7:0] (PC[7:0]) are bidirectional data pins controlled by the R/W signal.
The eight port D bits (PD[7:0]) can be used for general-purpose I/O, for the SCI and
SPI subsystems, or for bus data direction control. Port D can be read at any time. In-
puts return the sensed levels at the pin; outputs return the input level of the port D pin
drivers. If port D is written, the data is stored in an internal latch, and can be driven only
if port D is configured for general-purpose output. This port shares functions with the
on-chip SCI and SPI subsystems, while bits 6 and 7 control the direction of data flow
on the bus in expanded and special test modes.
