When the MST bit in the ICCR1 register is set to 0, the transfer clock is the external clock input from the SCL
pin. When the MST bit in the ICCR1 register is set to 1, the transfer clock is the internal clock selected by the
CKS0 to CKS3 bits in the ICCR1 register and the transfer clock is output from the SCL pin.
Table 16.6 lists the Transfer Rate Examples.
