Figure 11 shows a block diagram of a PSD5XX family product. In this design the PSD503 is
used. The PSD503 is configured to 64K x 16 EPROM in MUX mode. The address and data
on the 80C186 are multiplexed so the PSD503 latches the address internally. The address
lines A16 and A17 are internally latched using PA6 and PA5 from the PSD503 ports. Ports
PC0 – PC7, PD0 – PD7, PE3 and PE4 on the PSD503 are used to output the address
A0 – A17 externally to be used by the 128K x 16 SRAM external to the PSD503 device.
PA0 through PA3 are used as timer outputs to provide clocks for the stepper motor control.
Figure 12 shows the schematic for the processor connection to the PSD503 and Figure 13
shows a schematic for a typical stepper motor control unit interface to the PSD503. The
stepper motor interface control uses PB0 – PB5 to control the four L297 stepper motor
control chips. PB0 and PB1 are used to enable and disable the four axis of the motion. PB2
through PB5 are used to control the direction of the motor motion. PB0 through PB7 are
configured in the software. Figure 14 shows the *.ABL file used in this design.
