(1) MCG transmit buffer register (MC0TX)

Remark BRG:
Remark f
to f
This register is used to set the transmit data. A transmit operation starts when data is written to MC0TX while bit
7 (MC0PWR) of MCG control register 0 (MC0CTL0) is 1.
The data written to MC0TX is converted into serial data by the 8-bit shift register, and output to the MCGO pin.
Manchester code or bit sequential data can be set as the output code using bit 1 (MC0OSL) of MCG control
register 0 (MC0CTL0).
This register can be set by an 8-bit memory manipulation instruction.
Reset signal generation sets this register to FFH.
