*1 : R and C represent the pull-up resistance and load capacitance of the SCL and SDA lines, respectively. Vp
indicates the power supply voltage of the pull-up resistance and IOL indicates VOL guaranteed current.
*2 : The maximum tHDDAT must satisfy that it doesn't extend at least "L" period (tLOW) of device's SCL
signal.
*3 : A high-speed mode I2C bus device can be used on a standard mode I2C bus system as long as the device
satisfies the requirement of "tSUDAT ≥ 250 ns".
*4 : tCYCP is the APB bus clock cycle time. Please see the block diagram to refer the APB bus number which I
2C
is connected. To use I2C, set the APB bus clock at 8 MHz or more.
