TXIFL

Transmit Interrupt Fill Level (SEITX):

00 = Interrupt, if one or more Tx values can be stored

01 = Interrupt, if two or more Tx values can be stored

10 = Interrupt, if three or more Tx values can be stored

11 = Interrupt, if four or more Tx values can be stored

The first setting (TXIFL = 00) should be used, if the DMA Controller

is used for transferring values for TXSEI transmissions.

R/W

13:12

RXIFL

Receive Interrupt Fill Level (SEIRX):

00 = Interrupt, if one or more Rx values are stored

01 = Interrupt, if two or more Rx values are stored

10 = Interrupt, if three or more Rx values are stored

11 = Interrupt, if four or more Rx values are stored

The first setting (RXIFL = 00) should be used, if the DMA Controller

is used for transferring values from TXSEI receptions.

R/W

SILIE

SEI IDLE Interrupt Enable:

0 = Disable SIDLE as an interrupt source for SEIEXC

1 = Enable SIDLE as an interrupt source for SEIEXC

R/W

SOEIE

SEI Overflow Error Interrupt Enable:

0 = Disable SEOE as an interrupt source for SEIEXC

1 = Enables SEOE as an interrupt source for SEIEXC

R/W

SUEIE

SEI Underflow Error Interrupt Enable:

0 = Disable SEUE as an interrupt source for SEIEXC

1 = Enables SEUE as an interrupt source for SEIEXC

R/W

STFIE

SEI Transfer Format Error Interrupt Enable:

0 = Disable SETF as an interrupt source for SEIEXC

1 = Enable SETF as an interrupt source for SEIEXC



Wired to zero

SSIVAL

SSI valid

Determines if the Slave Select input signal is valid in master mode

or not. If valid, the SSI signal will be observed in master mode to

generate a transfer format error.

0 = SSI not valid in master mode

1 = SSI valid in master mode

R/W

IFSPSE

Inter Frame Space Prescaler Enable (valid only in master mode).

0 = IFS prescaler disabled

1 = IFS prescaler enabled

R/W

MSTR

Master / Slave Mode Select

0 = TXSEI is configured as slave

1 = TXSEI is configured as master
