Auto RTS Hardware Flow Control
Automatic RTS hardware flow control is used to prevent data overrun to the local receiver FIFO. The RTS#
output is used to request remote unit to suspend/resume data transmission. The auto RTS flow control
features is enabled to fit specific application requirement (see Figure 11):
Enable auto RTS flow control using EFR bit-6.
The auto RTS function must be started by asserting RTS# output pin (MCR bit-1 to logic 1 after it is enabled).
If needed, the RTS interrupt can be enabled through IER bit-6 (after setting EFR bit-4). The UART issues an
interrupt when the RTS# pin makes a transition from low to high: ISR bit-5 will be set to logic 1.
2.12
Auto CTS Flow Control
Automatic CTS flow control is used to prevent data overrun to the remote receiver FIFO. The CTS# input is
monitored to suspend/restart the local transmitter. The auto CTS flow control feature is selected to fit specific
application requirement (see Figure 11):
Enable auto CTS flow control using EFR bit-7.
If needed, the CTS interrupt can be enabled through IER bit-7 (after setting EFR bit-4). The UART issues an
interrupt when the CTS# pin is de-asserted (logic 1): ISR bit-5 will be set to 1, and UART will suspend
transmission as soon as the stop bit of the character in process is shifted out. Transmission is resumed after
the CTS# input is re-asserted (logic 0), indicating more data may be sent.

FIFO is Enabled by FCR bit-0=1
RTS# de-asserts when data fills above the flow
control trigger level to suspend remote transmitter.
Enable by EFR bit-6=1, MCR bit-1.
RTS# re-asserts when data falls below the flow
control trigger level to restart remote transmitter.
Enable by EFR bit-6=1, MCR bit-1.
