Register Name
Register Function
Data In
This Register is used to read the inputs on the port pins.
Control
A
0
sets the corresponding port pin in Address Out Mode.
A
1
sets the pin in MCU I/O Mode.
Data Out
Holds the output data in the MCU I/O Mode.
This register is used to control the data flow in the I/O ports.
A
0
sets the corresponding pin as an input pin.
A
1
sets the pin as an output pin.
Direction
Open Drain
A
0
sets the corresponding pin driver as a CMOS driver.
A
1
sets the pin driver as an Open Drain Driver.
PLD – I/O
A read only status register; a
1
indicates the corresponding pin
is configured as a PLD pin.
Macrocell Out
This register holds the outputs of the GPLD macrocells.
Page Register
A 4-bit register that supports paging.
1. Configures the PSD4XX SRAM to be accessed by
