When the last bit is transmitted, the TCM flag is set to a “1” if the transmit buffer is empty,
TEN is a “0”, or CTS handshaking is enabled and CTSx is “1”. If the transmit buffer is not
empty, TEN is a “1”, and CTS handshaking is disabled or CTS handshaking is enabled and CTSx
is low, the TCM flag is not set because transfer of the contents of the transmit buffer to the
transmit shift register occurs immediately.

Receive Method
(See Figure 2-113.)
Set up
Define the baud rate by writing a value from 0-255 into UxBRG.
Set the Receive Initialization Bit (RIN, bit 3 in the UxCON), to “1”.
Configure the data format and the clock selection by writing the appropriate value to UxMOD.
Set the Request-To-Send Enable Bit (RTS_SEL, bit 6 of UxCON), if RTS handshaking will be
used.
Set the Receive Enable Bit (REN, bit 1 in the UxCON), to “1”.
Operation
When a falling edge is detected on the URXDx pin, the value on the pin is sampled at the basic
clock rate, which is 16 times faster than the baud rate. If the pin is low for at least two cycles
of the basic clock, the start bit is detected. Sampling is again performed three times in the
approximate middle of the start bit. If two or more of the samples are low, the start bit is
deemed valid. If two or more of the samples are not low, the start bit is invalidated and the
UART again begins waiting for a falling edge on the URXDx pin.
Once a valid start bit has been detected, input data received through the URXDx pin is read one
bit at a time, LSB first, into the receive shift register. As is the case with the start bit, three
samples are taken in the approximate middle of each data bit, the parity bit, and the stop bit(s).
If two or more of the samples are low, a “0” is latched, and if two or more of the samples are
high, a “1” is latched.
When the number of bits specified by the data format has been received and the last stop bit is
