16.3.7
The serial status register 2 (SCSSR2) is a 16-bit register. The upper 8 bits indicate the number of
receive errors in the data of the SCFRDR2, and the lower 8 bits indicate SCIF operating state.
The CPU can always read and write the SCSSR2, but cannot write 1 to the status flags (ER,
TEND, TDFE, BRK, OPER, and DR). These flags can be cleared to 0 only if they have first been
read (after being set to 1). Bits 3 (FER) and 2 (PER) are read-only bits and cannot be written.

Description
Number of parity errors
These bits indicate the number of data items that
contain a parity error in the receive data stored in
the SCFRDR2. (The number of parity errors in
the SCFRDR2)
Number of framing errors
These bits indicate the number of data items that
contain a framing error in the receive data stored
in the SCFRDR2. (The number of framing errors
in the SCFRDR2)
