Product data sheet
MR2[4] is the bit that allows the transmitter to be controlled by the CTS pin (IP0 or IP1).
When this bit is set to one AND the CTS input is driven HIGH, the transmitter will stop
sending data at the end of the present character being serialized. It is usually the RTS
output of the receiver that will be connected to the transmitter’s CTS input. The receiver
will set RTS HIGH when the receiver FIFO is full AND the start bit of the 9th or 17th
character is sensed. Transmission then stops with 9 or 17 valid characters in the receiver.
When MR2[4] is set to one, CTSN must be at zero for the transmitter to operate. If MR2[4]
is set to zero, the IP pin will have no effect on the operation of the transmitter. MR1[7] is
the bit that allows the receiver to control OP0. When OP0 (or OP1) is controlled by the
receiver, the meaning of that pin will be.

For operation at elevated temperatures, the device must be derated based on 150 C maximum junction
temperature.
Parameters are valid over specified temperature range.
This product includes circuitry specifically designed for the protection of its internal devices from damaging
effects of excessive static charge. Nonetheless, it is suggested that conventional precautions be taken to
avoid applying any voltages larger than the rated maxima.
