Preliminary Information
PSD9XX Family
51
The
PSD9XX
Functional
Blocks
(cont.)
9.4.6 Port C – Functionality and Structure
Port C can be configured to perform one or more of the following functions (see Figure 21):
t MCU I/O Mode
t PLD Input – Input to the PLDs.
t Address In – Additional high address inputs using the Input Micro
Cells.
t In-System Programming – JTAG port can be enabled for programming/erase of the
PSD9XX 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 C pins can be configured in Open Drain Mode
t Battery Backup features – PC2 can be configured as a Battery Input (Vstby) pin.
PC4 can be configured as a Battery On Indicator output
pin, indicating when Vcc is less than Vbat.
Port C does not support Address Out mode, and therefore no Control Register is required.
Pin PC7 may be configured as the DBE input in certain microcontroller interfaces.
9.4.7 Port D – Functionality and Structure
Port D has three I/O pins. See Figure 22. This port does not support Address Out mode,
and therefore no Control Register is required. Port D can be configured to perform one or
more of the following functions:
t MCU I/O Mode
t GPLD Output – Combinatorial PLD output (external chip selects)
t PLD Input – direct input to PLDs
t Slew rate – pins can be set up for fast slew rate
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.
