5 V, 3.3 V and 2.5 V quad UART, 5 Mbit/s (max.) with 64-byte FIFOs
6.2 Hardware ow control
Hardware ow control is comprised of auto-CTS and auto-RTS. Auto-CTS and auto-RTS
can be enabled/disabled independently by programming EFR[7:6].
With auto-CTS, CTS must be active before the UART can transmit data.
Auto-RTS only activates the RTS output when there is enough room in the FIFO to receive
data and de-activates the RTS output when the RX FIFO is sufciently full. The halt and
resume trigger levels in the TCR determine the levels at which RTS is
activated/deactivated.
If both auto-CTS and auto-RTS are enabled, when RTS is connected to CTS, data
transmission does not occur unless the receiver FIFO has empty space. Thus, overrun
errors are eliminated during hardware ow control. If not enabled, overrun errors occur if
the transmit data rate exceeds the receive FIFO servicing latency.
