(6) I2C Timing
(VCC
= 3.0V, 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 I2C clock control register ICCR bit 4 and bit 3 (CS4 and CS3). For details, please refer to
the H/W manual register explanation.
*3 : N is defined in the I2C clock control register ICCR bit 2 to bit 0 (CS2 to CS0).
*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.
