DRIEn
Interrupt enable bit for data register empty (only UART and SPI mode).
0
Interrupt from DREn is inhibited (use polling)
1
When DREn is set, request an interrupt
TXCIEn
Interrupt enable bit for transmit complete (only UART and SPI mode).
0
Interrupt from TXCn is inhibited (use polling)
1
When TXCn is set, request an interrupt
RXCIEn
Interrupt enable bit for receive complete (only UART and SPI mode).
0
Interrupt from RXCn is inhibited (use polling)
1
When RXCn is set, request an interrupt
WAKEIEn
Interrupt enable bit for asynchronous wake in STOP mode. When device
is in stop mode, if RXDn goes to low level an interrupt can be requested
to wake-up system. (only UART mode). At that time the DRIEn bit and
USInST1 register value should be set to
‘0b’ and “00H”, respectively.
0
Interrupt from Wake is inhibited
1
When WAKEn is set, request an interrupt
TXEn
Enables the transmitter unit (only UART and SPI mode).
0
Transmitter is disabled
1
Transmitter is enabled
RXEn
Enables the receiver unit (only UART and SPI mode).
0
Receiver is disabled
1
Receiver is enabled
USInEN
Activate USIn function block by supplying.
0
USIn is disabled
1
USIn is enabled
DBLSn
This bit selects receiver sampling rate (only UART).
0
Normal asynchronous operation
1
Double Speed asynchronous operation
