9.4.6 Port D – Functionality and Structure
Port D has four I/O pins. See Figure 22. Port D can be configured to program one or more
of the following functions:
t MCU I/O Mode
t PLD Input – direct input to PLD
Port D pins can be configured in PSDsoft as input pins for other dedicated functions:
t PD0 – ALE, as address strobe input
t PD1 – CLKIN, as clock input to the PLD and APD counter
t PD2 – CSI, as active low chip select input. A high input will disable the
Flash/SRAM and CSIOP.
t PD3 – WRH, as active low Write Enable (high byte) input or as DBE input from
68HC912
9.4.7 Port E – Functionality and Structure
Port E can be configured to perform one or more of the following functions (see Figure 23):
t MCU I/O Mode
t In-System Programming – JTAG port can be enabled for programming/erase of the
PSD4000 device. (See Section 9.6 for more information on JTAG programming.)
Pins that are configured as JTAG pins in PSDsoft will not be available for other I/O
functions.
t Open Drain – Port E pins can be configured in Open Drain Mode
t Battery Backup features – PE6 can be configured as a Battery Input (Vstby) pin.
PE7 can be configured as a Battery On Indicator output
pin, indicating when Vcc is less than Vbat.
t Latched Address Output – Provided latched address (A7-0) output
