The  value  in  this  register  is  used  to  generate  internal  baud  rate  in  asynchronous 
mode or to generate SCKn 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 USInSAR register, USInBD register is used for slave 
address register when the USIn I2C mode.

USInDR[7:0] 

The  USIn  transmit  buffer  and  receive  buffer  share  the  same  I/O  address  with  this 
DATA  register.  The  transmit  data  buffer  is  the  destination  for  data  written  to  the 
USInDR  register.  Reading  the  USInDR  register  returns  the  contents  of  the  receive 
buffer. 
Write to this register only when the DREn flag is set. In SPI master mode, the SCK 
clock is generated when data are written to this register.
