9.4.6 Port D – Functionality and Structure
Port D has four I/O pins. See Figure 27. Port D can be configured to program one more of
the following functions:
J
MCU I/O Mode
J
CPLD Input – direct input to CPLD, no Input Micro
Cells
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 Micro
Cells Flip Flops and APD counter
J
PD2 – CSI, as active low chip select input. A high input will disable the
Flash/SRAM and CSIOP.
J
PD3 – 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 28):
J
MCU I/O Mode
J
In-System Programming – JTAG port can be enabled for programming/erase of the
PSD8XX device. (See Section 9.6 for more information on JTAG programming.)
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.
