Limitations

The TFT LCD module connector supports RGB mode or FMC mode only at the same time.
The signal INT is used both for TFT LCD and DSI display connectors. When RGB mode
TFT LCD is used, STM32L4R9AII6 cannot access onboard SRAM and NOR Flash memory.

PMOD connector

The P1 PMOD-standard connector is available on the STM32L4R9I-EVAL board to support
flexibility in small form factor applications. The PMOD connector implements the PMOD
type 2A and 4A on the STM32L4R9I-EVAL board.
