CTS (Clear-to-Send) Function
As a transmitter, the UART can be configured to recognize the
Clear-to-Send (CTSx) input as a handshaking signal. This is en-
abled by setting the CTS Function Enable Bit (bit 5 of UxCON) to
“1”. If CTS function is enabled, even when transmission is enabled
and the UARTx transmit buffer register is filled with the data, the
transmission never starts; but it will start when inputting “L” to the
CTSx pin.
Figures 27 and 28 show the UARTx transmit timings.

This timing applying to the conditions:
Character length = 8 bits
Parity enabled
1 stop bit
UART Receive Operation
Reception is enabled when the Receive Enable Bit is “1”. Detec-
tion of the start bit makes transfer clocks generated and the data
reception starts in the LSB first.
When using 9-bit character length, read the received data from the
UARTx receive buffer register 2 (high-order byte) first before the
UARTx receive buffer register 1 (low-order byte).
Reception requires the following setup:
(1) Define a baud rate by setting a value n (n = 0 to 255) into
UARTx baud rate generator (addresses 003116, 003916).
(2) Set the Receive Initialization Bit (bit 3 of UxCON) to “1”.
(3) Configure the data format and clock selection by setting the
UARTx mode register.
(4) Set the RTS Function Enable Bit (bit 5 of UxCON) if RTS func-
tion will be used.
(5) Set the Receive Enable Bit (bit 1 of UxCON) to “1”.

UART Transmit Operation
Transmission starts when the Transmit Enable Bit is “1” and the
Transmit Buffer Empty Flag is “0”. Additionally, when CTS function
enabled, the CTSx pin must be “L” to be started. The data in which
Start Bit and Stop Bit or Parity Bit are also added is transmitted
from the low-order byte sequentially. When using 9-bit character
length, set the data into the UARTx transmit buffer register 2
(high-order byte) first before the UARTx transmit buffer register 1
(low-order byte).
Once the transmission starts, the Transmit Enable Bit, the Trans-
mit Buffer Empty Flag and the CTSx pin state (when this is
enabled) could not be checked until the transmission in progress
has ended.
Transmission requires the following setup:
(1) Define a baud rate by setting a value n (n = 0 to 255) into
UARTx baud rate generator (addresses 003116, 003916).
(2) Set the Transmit Initialization Bit (bit 2 of UxCON) to “1”. This
will set the UARTx status register to “0316”.
(3) Select the interrupt source with the Transmit Interrupt Source
Select Bit (bit 4 of UxCON).
(4) Configure the data format and clock selection by setting the
UARTx mode register.
(5) Set the CTS Function Enable Bit (bit 5 of UxCON) if CTS func-
tion will be used.
(6) Set the Transmit Enable Bit (bit 0 of UxCON) to “1”.
If updating a value of UARTx baud rate generator while the data is
being transmitted, be sure to disable the transmission before up-
dating. If the former data remains in the UARTx transmit buffer
registers 1 and 2 at retransmission, an undefined data might be
output.
