Section 18 Serial Communication Interface with FIFO (SCIF)
18.3.8
SCSSR is a 16-bit readable/writable register that indicates SCIF states. The ORER, TSF, ER,
TDFE, BRK, RDF, or DR flag cannot be set to 1. These flags can be cleared to 0 only if they have
first been read (after being set to 1). The flags TEND, FER, and PER are read-only bits and cannot
be modified.
