What is the depth of the UART RX FIFO for the LPC54102? Where, specifically, can I find this information?

Hi,

As you know that the LPC5410x family has dedicated FIFO system for usart and SPI, the FIFO size is case by case, which are saved in a register called USART FIFO global control register (FIFOCTLUSART), pls read RXFIFOTOTAL/TXFIFOTOTAL bits of FIFOCTLUSART in your application code to know the transmitter/receiver FIFO size.

Hope it can help you
