FX3 Overview
Table 3-1. Block IO Selection
Note: Depending on the configuration, one of the columns of the table will be selected
Note:
(1) NC stands for Not Connected. Blk IOs 30-32,45 are Not Connected
(2) Charger detect is output only.
(3) GPIF IO are further configured into interface clock, control lines, address lines and data lines,
car-kit UART lines depending on the desired total number of GPIF pins, number of data lines and
address lines, whether the address and data lines need to be multiplexed and the car-kit mode.
Depending on the GPIF configuration selected by the user, some of the GPIF IO may remain
unconnected and may only be used as GPIOs.
