8.2 Memory Maps
The width of the GPIO port defines how many bits are implemented in each of the GPIO registers. Based
on this and the default function of each of the GPIO pins, the reset values of the GPIOx_PUR and
GPIOx_PER registers will change from port to port. Tables
4-29
through
4-34
define the actual reset
values of these registers.
8.3 Configuration
There are six GPIO ports defined on the 56F8357/56F8157. The width of each port and the associated
peripheral function is shown in
Table 8-1
and
Table 8-2.
The specific mapping of GPIO port pins is
shown in
Table 8-3
.
