Value
0 Transmit-data-empty interrupt request (TXI) is disabled
(initial value)
1 Transmit-data-empty interrupt request (TXI) is enabled
0 Receive-data-full interrupt (RXI) and receive-error
interrupt (ERI) requests are disabled (initial value)
1 Receive-data-full interrupt (RXI) and receive-error
interrupt (ERI) requests are enabled
0 Transmitter disabled (initial value)
1 Transmitter enabled
0 Receiver disabled (initial value)
1 Receiver enabled
0 Multiprocessor interrupts are disabled (nomal receive
operation) (initial value).
MPE is cleared to 0 when MPIE is cleared to 0, or the
multiprocessor bit (MPB) is set to 1 in receive data.
1 Multiprocessor interrupts are enabled. Receive-data-full
interrupt requests (RXI), receive-error interrupt requests
(ERI), and setting of the RDRF, FER, and ORER status
flags in the serial status register (SSR) are disabled until
the multiprocessor bit is set to 1.
0 Transmit-end interrupt (TEI) requests are disabled (initial
value)
1 Transmit-end interrupt (TEI) requests are enabled
