(10) Port output mode register 6 (POM6)
This register sets the output mode of P60 and P61 in 1-bit units.
When using the P60/TxD6/SCLA0 pin as the data output of serial interface UART6/DALI, clear POM60 to 0.
This register can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
