Description
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.
0: Low level is output
1: High level is output
Reserved
This bit is always read as 0. The write value should
Serial Port Break Data
Controls the TXD pins together with the TE bit in
SCSCR.
However, the TXD pin function should be selected with
the Pin Function Controller (PFC).
This bit is write-only bit. Undefined value is read.
