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:
J
MCU I/O Mode
J
PLD Input
direct input to PLD
Port D pins can be configured in PSDsoft as input pins for other dedicated functions:
J
PD0
ALE, as address strobe input
J
PD1
CLKIN, as clock input to the PLD and APD counter
J
PD2
CSI, as active low chip select input. A high input will disable the
Flash/SRAM and CSIOP.
J
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):
J
MCU I/O Mode
J
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.
J
Open Drain
Port E pins can be configured in Open Drain Mode
J
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.
