FX3 Overview
Table 3-2. Block IO override as simple/complex GPIO
Note: For each pin ‘n’ in column 1, one of column 2, 3 or 4 of the corresponding row will be selected based on the simple/override values for the corresponding pin
Note:
(1) Pins [30-32] are used as PMODE [0-2] inputs during boot. After boot, these are available as
GPIOs.
