Serial Channel (SIO)
Send buffer 1
I/O interface mode with SCLK input (normal mode):
The following example describes the case a 4-byte data stream is transmitted:
SC0FCNF <4:0> = 01001: Allows continued transmission after reaching the fill level.
SC0TFC <1:0> = 00: Clears the transmit FIFO and sets the condition of interrupt generation.
SC0TFC <7:6> = 11: Sets the interrupt to be generated at fill level 0.
In this condition, data transmission can be initiated along with the input clock by setting the
transfer mode to half duplex, writing 4 bytes of data to the transmit FIFO, and setting the <TXE>
bit to "1." When the last transmit data is moved to the send buffer, the transmit FIFO interrupt is
generated.
