When this bit is set to 1, reception is enabled.
MPIE
Multiprocessor Interrupt Enable (enabled only when the
MP bit in SMR is 1 in asynchronous mode)
When this bit is set to 1, receive data in which the
multiprocessor bit is 0 is skipped, and setting of the
RDRF, FER, and OER status flags in SSR is disabled.
On receiving data in which the multiprocessor bit is 1, this
bit is automatically cleared and normal reception is
resumed. For details, refer to section 16.6, Multiprocessor
Communication Function.
