GPIO Subsystem Register Descriptions (Continued)

5.16.2.11 GPIO Input Filter Enable (GPIO[x]_IN_FLTR_EN)

These registers control the input filter function enable for the low (GPIO[15:0]) and high (GPIO[31:16]) banks of GPIOs. If

the feature bit is high, the filter function is enabled. If the feature bit is low, the filter function is disabled.The reset value

forces all the filter functions to be disabled. (These registers use atomic programming, see Section 5.16.1 on page 436 for

details.)
