6.8 DMA operation
The SC16C550 FIFO trigger level provides additional flexibility to the user for block
mode operation. The user can optionally operate the transmit and receive FIFOs in
the DMA mode (FCR[3]). The DMA mode affects the state of the RXRDY and TXRDY
output pins. Tables
6
and
7
show this.
