This is the data register of the serial interface.
During writing operation
When "1" is written: High level
When "0" is written: Low level
Writes serial data will be output to SOUT terminal. From the SOUT terminal, the data converted to
serial data as high (VDD) level bit for bits set at "1" and as low (VSS) level bit for bits set at "0".
Perform data writing only while the serial interface is halted (i.e., the synchronous clock is neither
being input or output).
At initial reset, these registers will be undefined.
During reading operation
When "1" is read: High level
When "0" is read: Low level
The serial data input from the SIN terminal can be read by this register.
The data converted to parallel data, as high (VDD) level bit "1" and as low (VSS) level bit "0" input from
SIN terminal. Perform data reading only while the serial interface is halted (i.e., the synchronous clock
is neither being input or output).
At initial reset, these registers will be undefined.
