1. Write to this register while serial interface is neither transmitting nor receiving.
2. Use the MOV instruction to write to this register.
3. Write to this register after setting bits SM31 to SM30 in the S3C register.
1. Write to this register while serial interface is neither transmitting nor receiving.
2. To receive data, set the corresponding port direction bit for SIN3 to 0 (input mode).

1. Make sure this register is written to by the next instruction after setting the PRC2 bit in the PRCR register to 1
2. When the SM32 bit is set to 1, the target pin goes to a high-impedance state regardless of which functions of the
3. Set the SM33 bit to 1 (SOUT3 output, CLK3 function) and the corresponding port direction bit to 0 (input mode).
4. Set the SM33 bit to 1 (SOUT3 output, CLK3 function).
5. When changing bits SM31 to SM30, set the S3BRG register.

Assuming that set value = n, S3BRG divides the count
source by n + 1
Transmission/reception starts by writing transmit data to this register.
After transmission/reception finishes, receive data can be read by reading this register.
