(5) SO1n output (see Figures 16-1 and 16-2)
414
The status of the SO1n output is as follows if bit 7 (CSIE1n) of serial operation mode register 1n (CSIM1n) is
cleared to 0.
Notes 1.
Caution If a value is written to TRMD1n, DAP1n, and DIR1n, the output value of SO1n changes.
Remark
TRMD1n = 0
TRMD1n = 1

n = 0:
n = 0, 1:
The actual output of the SO10/P12 or SO11/P02 pin is determined according to PM12 and P12
or PM02 and P02, as well as the SO1n output.
