78K0/Kx2-L
(1) Transmit buffer register 1n (SOTB1n)
R01UH0028EJ0400 Rev.4.00
Sep 27, 2010
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).
Remarks 1. 78K0/KA2-L (25, 32-pin products): n = 1
2. The SSI11 pin is available only in 78K0/KA2-L (25, 32-pin products) and 78K0/KC2-L (48-pin products).
2. In the slave mode, transmission/reception is started when data is written to SOTB11 with a low
78K0/KB2-L:
