General Purpose I/O Ports
Ports 0 and 1 provide up to 10 versatile GPIO pins that can be read or written (the number of pins depends on package type).
Figure 12-1. Block Diagram of GPIO Port (one pin shown)
Port 0 is an 8-bit port; Port 1 contains 2 bits, P1.1
–
P1.0 in the CY7C63231 and CY7C63221A-XC parts. Each bit can also be
selected as an interrupt source for the microcontroller.
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
.
Bit [7:0]: P0[7:0]
