1. Enabling the transmit interrupt (bit
STAT register) does not make the device ready for
transmitter-related interrupts. The receiver interrupt

register) must also be enabled.

2. When using the device in full-duplex mode under in-
terrupts (both transmit and receive interrupts enabled),
a small window exists where a transmit or receive in-
terrupt may be lost. This situation occurs when an in-
terrupt is generated by one side (either the transmitter
or receiver) and, before the interrupt is serviced, an-
other interrupt is generated by the other side. The sec-
ond interrupt may be lost.
Workaround
transmitter interrupts when using the ASCI in full-
duplex mode. Use the transmitter in polled mode and
the receiver in interrupt mode for full duplex
operation. In half-duplex operation, this anomaly does
not create a problem.
: The only workaround is not to use
