Bit 3
SIR
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.
SCL
Note: This bit has to be set to "1" during the MCL mode and the Timer 3 mode 10 or 11
