Notes: Only ch.16 and ch.17 are standard mode/high-speed mode correspondence. In ch.0, ch.1, ch.4, and ch.8 to ch.12, only a
standard mode is correspondence.
*1: R and CL represent the pull-up resistance and load capacitance of the SCL and SDA output lines,
respectively.
Vp shows that the power-supply voltage of the pull-up resistor and IOL shows the VOL guarantee current.
*2: The maximum tHDDAT only has to be met if the device does not extend the "L" width (tLOW) of the 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: tNFT=(NFCR:NFT[4:0]+1) x 2 x tCLK_LCP0A (ch.0, ch.1, ch4)
tNFT=(NFCR:NFT[4:0]+1) x 2 x tCLK_LCP1A (ch.8 to ch.12)
tNFT=(NFCR:NFT[4:0]+1) x 2 x tCLK_COMP (ch.16 to ch.17)
