2.10 FlexIO header
On the FRDM-MCXN947 board, one 28-pin FlexIO header (J8) is provided to support the LCD display and
camera applications. Table 21 describes the pinout of the FlexIO header.
The FlexIO header is intended to support the Mikroe TFT Proto 5” Capacitive display and the LCD-PAR-
S035 display. These displays support 3 V I/O only, so care must be taken to ensure that ALL pins used on this
connector are configured for 3V3 operation (this includes Ports 0, 1, 2 and 4).
A few of the signals on the FlexIO connector are shared signals. Before using the FlexIO connector with other
modules, be sure to check the schematics to determine if there are overlapping signals with the other modules
intended to be used and that the necessary FlexIO signals are correctly selected via the zero-ohm resistor
selections.
