(7) I2C timing
(Vcc = 5.0 V, AVSS = VSS = 0.0 V, TA = –40
°C to +85 °C)
*1 : For information in tinst, 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 greater than SCL "L" width, SDA and SCL output (Standard) value is based on
hypothesis when rising time is 0 ns.
