WebSTM32 GPIO Ports. Each of the general-purpose I/O ports has two 32-bit configuration registers, two 32-bit data registers, a 32-bit set/reset register, a 16-bit reset register, and a 32-bit locking register. Each I/O port bit is freely programmable, however, the I/O port registers have to be accessed as 32-bit words (half-word or byte accesses ... WebEach I/O port has three registers directly associated with the operation of the port: TRIS, PORT and LAT. Each I/O port pin has a corresponding bit in these registers. Depending on the PIC32MX device variant, up to seven I/O ports are available. Through out this section, the letter ‘x’, denotes any or all port module instances.
