Description
Transmit-data-empty interrupt request (TXI) is disabled
Transmit-data-empty interrupt request (TXI) is enabled
Receive-data-full (RXI) and receive-error (ERI) interrupt requests are disabled
Receive-data-full (RXI) and receive-error (ERI) interrupt requests are enabled
Transmitting is disabled
Transmitting is enabled
Receiving is disabled
Receiving is enabled
Multiprocessor interrupts are disabled (normal receive operation)
[Clearing conditions]
1. Clearing MPIE to 0
2. When data with MPB = 1 is received
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 requests (TEI) are disabled
Transmit-end interrupt requests (TEI) are enabled
