MB89530 Series
44
(7) I2C Timing
(VCC
= 3.0 V, AVss = Vss = 0 V, TA = 40 °C to +85 °C)
Notes :
For tinst refer to “ (4) Instruction Cycle”.
The value “m” in the above table is the value from the shift clock frequency setting bits (CS4-CS3) in the
I2C clock control register “ICCR”. For details, refer to the register description in the hardware manual.
The value ’n’ in the above table is the value from the shift clock frequency setting bits (CS2-CS0) in the
I2C clock control register “ICCR”. For details, refer to the register description in the hardware manual.
tDOSU appears when the interrupt period is longer than the SCL “L” width.
The rated values for SDA and SCL assume a start up time of 0 ns.
