Correct operation cannot be guaranteed since the transfer rate is beyond the I2C bus
interface specification (normal mode: maximum 100 kHz, high-speed mode: maximum
400 kHz).

Description
Transfer Clock Select 3 to 0
In the master mode, these bits should be set
according to the necessary transfer rate (see table
17.2). In the slave mode, they are used to secure
the data setup time in transmit mode. The data
setup time is 10 tcyc if CKS3 is cleared to 0 and
20 tcyc if CKS3 is set to 1.
