Transmit error

transmit error occurs, the SO1 pin goes high.

SIO to halt. Setting SIO1CR1<SIOINH> to “1” initializes the SIO1CR1<SIOS> and
SIO1SR registers; no other registers or bits are initialized.
Example of setting the transmit mode (Transmit mode, external clock, and 8-byte
transfer).
During operation on an external clock, the following case may be detected as a
