I2C Timing
*1 : R,C : Pull-up resistor and load capacitor of the SCL and SDA lines.
*2 : The maximum tHDDAT have only to be met if the device does not stretch the “L” width (tLOW) of the SCL signal.
*3 : A Fast-mode I2C-bus device can be used in a Standard-mode I2C-bus system, but the requirement
tSUDAT
≥ 250 ns must then be met.
*4 : For use at over 100 kHz, set the peripheral clock 1 to at least 6 MHz.
(TA = -40C to 125C, VCC = AVCC = 3.0V to 5.5V,VSS = AVSS =0V)
