6.2
The following registers are associated with the General Purpose I/O (GPIO) and are listed in address order. The register
descriptions have an associated register table showing the bit structure for that register. The bits in the tables that are grayed
out are reserved bits and are not detailed in the register descriptions that follow. Always write reserved bits with a value of 0.
For a complete table of General Purpose I/O registers, refer to the
For a selected GPIO block, the individual registers are addressed in the
names, the ‘x’ is the port number, configured at the PSoC device level (x = 0 to 4 typically). All register values are readable,
except for the PRTxDR register; reads of this register return the pin state instead of the register bit state.
6.2.1
The Port Data Register (PRTxDR) allows for write or read
access of the current logical equivalent of the voltage on the
pin.
Bits 7 to 0: Data[7:0]. Writing the PRTxDR register bits set
the output drive state for the pin to high (for Data = 1) or low
(Data = 0), unless a bypass mode is selected (see
Bypass on page
6.2.2
The Port Interrupt Enables (PRTxIE) registers enable or dis-
able interrupts from individual GIPIO pins.
Bits 7 to 0: InterruptEnables[7:0]. These bits enable the
corresponding port pin interrupt. Only four LSB pins are
used since this port has four pins.

Reading the PRTxDR register returns the actual pin state,
as seen by the input buffer. This may not be the same as the
expected output state, if the load pulls the pin more strongly
than the pin’s configured output drive. See

‘0’ is port pin interrupt disabled for the corresponding pin.
‘1’ is port pin interrupt enabled for the corresponding pin.
Interrupt mode is determined by the IOINT bit in the
