(5) SO1 output
Caution If a value is written to the TRMD1, DAP1, and DIR1 bits, the output value of the SO1 bit changes.
The status of the SO1 output is as follows if bit 7 (CSIE1) of serial operation mode register 1 (CSIM1) is cleared
to 0.
Notes 1. The PM21, P21, and SSE1 bits and the SS1 pin must also be set to actually produce an output from
TRMD1 = 0
TRMD1 = 1
TRMD1
2. Status after reset
the SO1/P21 pin.
