HIGH PERFORMANCE 2.97V TO 5.5V OCTAL UART
Receive FIFO level byte count from 0x00 (zero) to 0x40 (64). It gives an indication of the number of characters
in the receive FIFO. The FIFO level byte count register is read only. The user can take advantage of the FIFO
level byte counter for faster data unloading from the receiver FIFO, which reduces CPU bandwidth
requirements.
An 8-bit value written to this register, sets the RX FIFO trigger level from 0x00 (zero) to 0x40 (64). The RX
FIFO trigger level generates an interrupt whenever the receive FIFO level rises to this preset trigger level.
