(1) Transmit buffer register 1n (SOTB1n)
SI11/SDAA0/P61
SCK11/SCLA0/P60
Notes 1.
This register sets the transmit data.
Transmission/reception is started by writing data to SOTB1n when bit 7 (CSIE1n) and bit 6 (TRMD1n) of serial
operation mode register 1n (CSIM1n) is 1.
The data written to SOTB1n is converted from parallel data into serial data by serial I/O shift register 1n, and
output to the serial output pin (SO1n).
SOTB1n can be written or read by an 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
Cautions 1. Do not access SOTB1n when CSOT1n = 1 (during serial communication).

Note 1
2. The SSI11 pin is available only in 48-pin products of 78K0/KC2-L.
By MUXSEL register setting, SCK11, SI11, and SO11 can be assigned as P40, P41, and P120,
respectively.
