Chapter 10 Inter-Integrated Circuit (S08IICV2)
For example, if the bus speed is 8 MHz, the table below shows the possible hold time values with different
ICR and MULT selections to achieve an IIC baud rate of 100kbps.

IIC Multiplier Factor. The MULT bits define the multiplier factor, mul. This factor, along with the SCL divider,
generates the IIC baud rate. The multiplier factor mul as defined by the MULT bits is provided below.
00 mul = 01
01 mul = 02
10 mul = 04

IIC Clock Rate. The ICR bits are used to prescale the bus clock for bit rate selection. These bits and the MULT
bits determine the IIC baud rate, the SDA hold time, the SCL Start hold time, and the SCL Stop hold time.
Table 10-5
The SCL divider multiplied by multiplier factor mul generates IIC baud rate.
SDA hold time is the delay from the falling edge of SCL (IIC clock) to the changing of SDA (IIC data).
SCL start hold time is the delay from the falling edge of SDA (IIC data) while SCL is high (Start condition) to the
falling edge of SCL (IIC clock).
SCL stop hold time is the delay from the rising edge of SCL (IIC clock) to the rising edge of SDA
SDA (IIC data) while SCL is high (Stop condition).

provides the SCL divider and hold values for corresponding values of the ICR.
SCL Start hold time = bus period (s)
SCL Stop hold time = bus period (s)
