SPB1DT Undefined R/W Clock Port Data in Serial Port
Specifies the data output through the SCK pin in the
serial port. Output should be enabled by the SPB1IO bit
(for details, refer to the SPB1IO bit description). When
output is enabled, the SPB1DT bit value is output
through the SCK pin.

W Serial Port Break Data
Controls the TXD pin by the TE bit in SCSCR.
However, TXD pin function should be selected by the
