Transfer data length: 8 bits
• SM36 bit in S3C register = 1 (internal clock) : fj/(2(n+1))
• SM36 bit = 0 (external clock) : Input from CLK3 pin
Before transmission/reception can start, meet the following requirements

Whether to start transmitting or receiving data begins with bit 0 or begins
with bit 7 can be selected
When the SM36 bit in the S3C register = 0 (external clock), the SOUT3 pin
output level while not transmitting can be selected.
Whether transmit data is output/input timing at the rising edge or falling
edge of transfer clock can be selected.
