(MM_CNT_PHASE_VAL0+1)/TCXO_CLK
(MM_CNT_PHASE_VAL1+1)/TCXO_CLK
(MM_CNT_PHASE_VAL2+1)/TCXO_CLK
(MM_CNT_PHASE_VAL3+1)/TCXO_CLK
Note: The condition of I2C clock cycle (I2C_CLK) is (TCXO_CLK/4) MHz ~ (TCXO_CLK/(MM_CNT+4)) MHz. The
MM_CNT is the sum of MM_CNT_PHASE_VAL0, MM_CNT_PHASE_VAL1, MM_CNT_PHASE_VAL2 and
MM_CNT_PHASE_VAL3 in full speed mode.
