SCL = 0 before BRG time out,
Bus collision occurs, Set BCLIF.
Set SEN, enable start
sequence if SDA = 1, SCL = 1
condition if SDA = 1, SCL=1
Set SEN, enable start
SDA sampled low before
START condition.
S bit and SSPIF set because
SDA = 0, SCL = 1
. Set BCLIF,
SDA goes low before the SEN bit is set.
S bit and SSPIF set because
SDA = 0, SCL = 1
SDA = 0, SCL = 1
Set BCLIF.

SEN cleared automatically because of bus collision.
SSP module reset into idle state.
SCL = 0 before SDA = 0,
Bus collision occurs, Set BCLIF.
