These pins make up Port C. These port pins are configurable, and
can have the following functions (see Figure 7):
1. PAD input—when configured as an input, a bit individually
2. PAD output—when configured as an output (i.e. there is an
These pins are the multiplexed, low-order address/data byte
(AD0-AD7). As inputs, address information is latched by the ALE/AS
signal and used internally by the PSD. The pins also serve as MCU
data bus inputs or outputs, depending on the MCU control signals
(RD, WR, etc.).
