Port 0 is an 8-bit port; Port 1 contains either 2 bits, P1.1–P1.0 in the CY7C63723, or all 8 bits, P1.7–P1.0 in the CY7C63743 parts.
Each bit can also be selected as an interrupt source for the microcontroller, as explained in Section 21.0.
The data for each GPIO pin is accessible through the Port Data register. Writes to the Port Data register store outgoing data state
for the port pins, while reads from the Port Data register return the actual logic value on the port pins, not the Port Data register
contents.
Each GPIO pin is configured independently. The driving state of each GPIO pin is determined by the value written to the pin’s
Data Register and by two associated pin’s Mode0 and Mode1 bits.
The Port 0 Data Register is shown in
Figure 12-2
, and the Port 1 Data Register is shown in
Figure 12-3
. The Mode0 and Mode1
bits for the two GPIO ports are given in
Figure 12-4
through
Figure 12-7
.
