Serial Interface Registers
5.3.4.12
Serial Interface Control Register 1 (SIC1)
In transmit mode (SDD = 1) shifting starts only if the transmit buffer has been loaded
(SRDY = 1).
Setting SIR bit loads the contents of the shift register into the receive buffer
(synchronous 8-bit mode only).
In MCL modes, writing a 0 to SIR generates a start condition and writing a 1 generates a stop
condition.
Auxiliary register address: '9'hex

SIR
Serial Interface Reset
SIR = 1, SSI inactive
SIR = 0, SSI active
SCD
Serial Clock Direction
SCD = 1, SC line used as output
SCD = 0, SC line used as input
Note:
This bit has to be set to '1' during the MCL mode and the Timer 3 mode 10 or 11
SCS1
Serial Clock source Select bit 1
SCS0
Serial Clock source Select bit 0
Note:
With SCD = '0' the bits SCS1 and SCS0 are insignificant
