(4) Serial operation condition setting
MASTER bit (Selection of external/internal SCK clock)
Set the master or slave mode. Select the internal clock for the serial clock (SCK) to set the serial operation to
master mode, and select the external clock to set the serial operation to slave mode.
If the master setting is selected, the serial operation will start and the serial clock will be outputted when start
setting is made by the serial start bits (TSTA1 and TSTA2 bits), and the operation will stop under the serial counter
stop condition. The serial clock selected by the clock selection bits (CK0, CK1 bit) will be outputted.
If the slave setting is selected, the serial operation will start automatically when the external clock is inputted. For
the 2- or 3-wired type, frequencies no higher than 200 kHz (fSCK) can be inputted as the external clock.
Selection of external or internal SCK
Note: Select the slave setting when the UART is selected.
Note: This bit is reset to "0" after a system reset.
