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 the on-board SRAM and NOR flash
memory.
6.31 Pmod™ connector
The Pmod™-standard connector (P1) is available on the STM32L4R9I-EVAL main board to
support flexibility in small form factor applications. The Pmod™ connector implements the
Pmod™ type 2A and 4A on the STM32L4R9I-EVAL main board.
