the transmitter. If this bit is a 1, the transmitter checks the state of
CTSN each time it is ready to begin sending a character. If it is
asserted (low), the character is transmitted. If it is negated (high),
the TxD output remains in the marking state and the transmission is
delayed until CTSN goes low. Changes in CTSN, while a character
is being transmitted, do not affect the transmission of that character.
This feature can be used to prevent overrun of a remote receiver.
MR2[3:2] – RxINT control field
Controls when interrupt arbitration for a receiver begins based on
RxFIFO fill level. This field allows interrupt arbitration to begin when
the RxFIFO is full, 3/4 full, 1/2 full or when it contains at least 1
character.
MR2[1:0] – Stop Bit Length Select
This field programs the length of the stop bit appended to the
transmitted character. Stop bit lengths of 9/16, 1, 1.5 and 2 bits can
be programmed for character lengths of 6, 7, and 8 bits. For a
character length of 5 bits, 1, 1.5 and 2 stop bits can be programmed.
In all cases, the receiver only checks for a mark condition at the
center of the first stop bit position (one bit time after the last data bit,
or after the parity bit if parity is enabled). If an external 1X clock is
used for the transmitter, MR2[1] = 0 selects one stop bit and MR2[1]
= 1 selects two stop bits to be transmitted.
Table 6. RxCSR and TxCSR – Receiver and Transmitter Clock Select Registers
Both registers consist of single 5 bit field that selects the clock source for the receiver and transmitter, respectively. The unused bits in this
register read b’111. The baud rates shown in the table below are based on the x1 crystal frequency of 3.6864MHz. The baud rates shown
below will vary as the X1 crystal clock varies. For example, if the X1 rate is changed to 7.3728 MHz all the rates below will double.
