to another station, the RDRF flag in SCSSR1 is set to 1. When the RDRF flag in SCSSR1
is set to 1, the exception handling routine reads the MPIE bit in SCSCR1, and skips the
receive data if the MPIE bit is 1. Skipping of unnecessary data is achieved by
collaborative operation with the exception handling routine.
