7.10.5.7 GPIO

Table 7-48, Table 7-49, and Table 7-50 present timing conditions, requirements, and switching characteristics for

GPIO.

For more details about features and additional description information on the device GPIO, see the

corresponding subsections within Signal Descriptions and Detailed Description sections.

Note

The device has multiple GPIO modules. GPIOn_x is generic name used to describe a GPIO signal,

where n represents the specific GPIO module and x represents one of the input/output signals

associated with the module.
