LPC213x UART1 RX/TX buffer

Started by jlowryspectrum March 10, 2005

Anyone know if I turn off the FIFO (U1FCR bit 0 = 0) will I still get
interrupts (if enabled) when a single character is received?

Or does turning off the FIFO disable receiving and transmitting
altogether? Thanks, Jeff.



An Engineer's Guide to the LPC2100 Series


See description of FIFO enable bit in Table 69 of User Manual:
"This bit must be set for proper UART0 operation"

Similarly Table 84 for UART1.
