Initial value : FFH
USI1BD[7:0]
The value in this register is used to generate internal baud rate in
asynchronous mode or to generate SCK1 clock in SPI mode. To
prevent malfunction, do not write ‘0’ in asynchronous mode and do
not write ‘0’ or ‘1’ in SPI mode.
NOTE) In common with USI1SAR register, USI1BD register is
used for slave address register when the USI1 I2C mode.
