SC16C652B
Dual UART with 32-byte FIFOs and IrDA encoder/decoder
6.9 DMA operation
The SC16C652B FIFO trigger level provides additional exibility 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
6.10 Loop-back mode
The internal loop-back capability allows on-board diagnostics. In the loop-back mode, the
normal modem interface pins are disconnected and recongured for loop-back internally
(see Figure 5). MCR[3:0] register bits are used for controlling loop-back diagnostic testing.
In the loop-back mode, the transmitter output (TX) and the receiver input (RX) are
disconnected from their associated interface pins, and instead are connected together
internally. The CTS, DSR, CD, and RI are disconnected from their normal modem control
inputs pins, and instead are connected internally to RTS, DTR, MCR[3] (OP2) and
