Multiprocessor Interrupt Enable

Multiprocessor interrupts disabled (normal reception performed)

[Clearing conditions]

• When the MPIE bit is cleared to 0

• When MPB = 1 data is received

Multiprocessor interrupts enabled

Receive interrupt (RXI) requests, receive error interrupt (ERI)

requests, and settingof the RDRF, FER, and ORER flags in SSR

are disabled until data with the multiprocessor bit set to 1 is received.

Clock Enable 1 and 0
