, see "(4) Instruction Cycle".
*2: M is defined in the ICCR CS4 and CS3 (bit 4 to bit 3). For details, please refer to the H/W manual register
explanation.
*3: N is defined in the ICCR CS2 to CS0 (bit 2 to bit 0)
*4: When the interrupt period is grater than SCL "L" width, SDA and SCL output (Standard) value is based on
hypothesis when rising time is 0 ns.
