The clear to send (CTS) pin, if enabled by the
ister, performs flow control on the outgoing transmit data stream. The CTS input pin is
sampled one system clock before beginning any new character transmission. To delay
transmission of the next data character, an external receiver must deassert CTS at least one
system clock cycle before a new data transmission begins. For multiple character trans-
missions, this operation is typically performed during the Stop bit transmission. If CTS
deasserts in the middle of a character transmission, the current character is sent com-
pletely.
The LIN-UART provides a Driver Enable (DE) signal for off-chip bus transceivers. This
feature reduces the software overhead associated with using a GPIO pin to control the
transceiver when communicating on a multi-transceiver bus such as RS-485.
Driver Enable is a programmable polarity signal which envelopes the entire transmitted
data frame including parity and stop bits as illustrated in Figure 17. The DE signal asserts
when a byte is written to the LIN-UART transmit data register. The DE signal asserts at
least one bit period and no greater than two bit periods before the Start bit is transmitted.
This allows a set-up time to enable the transceiver. The DE signal deasserts one system
clock period after the final
both time for data to clear the transceiver before disabling it, as well as the ability to deter-
mine if another character follows the current character. In the event of back to back char-
acters (new data must be written to the transmit data register before the previous character
is completely transmitted) the DE signal is not deasserted between characters. The
DEPOL bit in the LIN-UART control register 1 sets the polarity of the DE signal.
