9.7.3 SCLPC FIFO Registers—MBAR + 0x3C40
LPC uses a single FIFO that changes direction based on the Rx/Tx mode. Software controls direction change and flushes FIFO before
changing directions. FIFO memory is 512Bytes (32 x 128 ).
LPC FIFO is controlled by six 32-bit registers. These registers are located at an offset from MBAR of 0x3C40. Register addresses are relative
to this offset. Therefore, the actual register address is: MBAR + 0x3C40 + register address
Hyperlinks to the LPC FIFO registers are provided below:
