Multiprocessor interrupts disabled
[Clearing conditions]
• When the MPIE bit is cleared to 0
• When MPB= 1 data is received
Multiprocessor interrupts enabled
1
Receive data full interrupt (RXI) requests, receive error interrupt
(ERI) requests, and setting of the RDRF, FER, and ORER flags
in SSR are disabled until data with the multiprocessor bit set to
