(Cont.)
In Figure 15, the PSD3XX is configured to work directly with Intel’s 80C196KB
microcontroller, which is a 16-bit address/16-bit data bus processor. Address and data lines
multiplexed. In the example shown, all configuration bits are set. The PSD3XX is configured
to use PC0, PC1, PC2, and CSI/A19 as A16, A17, A18, and A19 inputs, respectively.
These signals are independent of the ALE pulse (latch-transparent). They are used as four
general-purpose logic inputs that take part in the PAD equations implementation.
Port A is configured to work in the special track mode, in which (for certain conditions)
PA0–PA7 tracks lines AD0/A0–AD7/A7. Port B is configured to generate CS0–CS7. In this
example, PB2 serves as a WAIT signal that slows down the 80C196KB during the access of
external peripherals. These 8-bit wide peripherals are connected to the shared bus of Port
A. The WAIT signal also drives the buswidth input of the microcontroller, so that every
external peripheral cycle becomes an 8-bit data bus cycle. PB3 and PB4 are open-drain
output signals; thus, they are pulled up externally.
