The SDA hold delay is equal to the CPU clock period multiplied by the SDA Hold value shown in
Table
The equation for SCL Hold values to generate the start and stop conditions from the IBFD bits is:
Freescale Semiconductor
MUL=1
9-5. The equation used to generate the SDA Hold value from the IBFD bits is:
SDA Hold = MUL x {scl2tap + [(SDA_Tap - 1) x tap2tap] + 3}
SCL Hold(start) = MUL x [scl2start + (SCL_Tap - 1) x tap2tap]
SCL Hold(stop) = MUL x [scl2stop + (SCL_Tap - 1) x tap2tap]
