7
Transmit interrupt
0
Transmit-data-empty interrupt request (TXI) is disabled
enable (TIE)
1
Transmit-data-empty interrupt request (TXI) is enabled
(Initial value)
6
Receive interrupt enable 0
Receive-data-full (RXI) and receive-error (ERI) interrupt requests are disabled
(RIE)
(Initial value)
1
Receive-data-full (RXI) and receive-error (ERI) interrupt requests are enabled
5
Transmit enable (TE) 0
Transmitting is disabled
(Initial value)
1
Transmitting is enabled
4
Receive enable (RE) 0
Receiving is disabled
(Initial value)
1
Receiving is enabled
3
Multiprocessor interrupt 0
Multiprocessor interrupts are disabled (normal receive operation) (Initial value)
enable (MPIE)
[Clearing conditions]
1. Clearing MPIE to 0
2. When data with MPB = 1 is received
1
Multiprocessor interrupts are enabled
Receive data full interrupt (RXI) and receive error interrupt (ERI) requests, and
setting of RDRF, FER, and ORER flags in SSR, are disabled until data with the
multiprocessor bit set to 1 is received.

Transmit-end interrupt 0
Transmit-end interrupt requests (TEI) are disabled
enable (TEIE)
1
Transmit-end interrupt requests (TEI) are enabled
(Initial value)
