(2) Serial clock selection register 1n (CSIC1n)
362
Address: FF81H After reset: 00H R/W
CSIC10
Cautions 1. Do not write to CSIC10 while CSIE10 = 1 (operation enabled).
Remark f
Symbol
This register specifies the timing of the data transmission/reception and sets the serial clock.
CSIC1n can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
Remark n = 0, 1
2. To use P10/SCK10/T
3. The phase type of the data clock is type 1 after reset.
