NOTES: Std. means Standard Mode and fast means Fast Mode.
1. The IIC data hold time(tSDAH) is minimum 0ns.
(IIC data hold time is minimum 0ns for standard/fast bus mode in IIC specification v2.1.)
Please check the data hold time of your IIC device if it's 0 nS or not.
2. The IIC controller supports only IIC bus device(standard/fast bus mode), not C bus device.
