4.2
This section shows the superset of pin control functions which may be present on V1 ColdFire devices.
Some devices may not include all of these controls. See the summary table earlier in the chapter for
specific capabilities for your device.
4.2.1
A set of registers (shown in
for the pins. They may also be used in conjunction with the peripheral functions on these pins. These
registers are associated with the parallel I/O ports and Rapid GPIO (RGPIO) ports, but operate
independently of both.
4.2.2
These registers control the pullups, slew rate, drive strength, and input filter for all the pins and may be
used for the peripheral functions (FEC, Mini-FlexBus, etc.) on these pins.
