Notes: 1. Clearing RE to 0 does not affect the receive flags (RDRF, FER, PER, ORER). These
Bit 3—Multiprocessor Interrupt Enable (MPIE): Enables or disables multiprocessor interrupts.
The MPIE setting is used only in asynchronous mode, and only if the multiprocessor mode bit
(MP) in the serial mode register (SCSMR) is set to 1 during reception. The MPIE setting is
ignored in synchronous mode or when the MP bit is cleared to 0.

Description
Multiprocessor interrupts are disabled (normal receive operation)
[Clearing conditions]
(1) MPE is cleared to 0 when MPIE is cleared to 0.
(2) The multiprocessor bit (MPB) is set to 1 in receive data.
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
(SCSSR) are disabled until data with a multiprocessor bit of 1 is received.
