High Speed Host Baud Rate Low
HSBAUDLOW non-zero: HSBAUDLOW indicates the SCL low time in High-speed mode according to
HSBAUDLOW equal to zero: The HSBAUD register is used to time TLOW, THIGH, TSU;STO, THD;STA and TSU;STA.. TBUF is timed by the BAUD register.
High Speed Host Baud Rate
This bit field indicates the SCL high time in High-speed mode according to the following formula. When HSBAUDLOW is zero, TLOW, THIGH, TSU;STO, THD;STA and TSU;STA are derived using this formula. TBUF is timed by the BAUD register.
Host Baud Rate Low
If this bit field is non-zero, the SCL low time will be described by the value written.
For more information on how to calculate the frequency, see SERCOM Clock Generation – Baud-Rate Generator.
Host Baud Rate
This bit field is used to derive the SCL high time if BAUD.BAUDLOW is non-zero. If BAUD.BAUDLOW is zero, BAUD will be used to generate both high and low periods of the SCL.
