SDA and SCL Rise Time
From SDA exiting the 30% to 70% of
V_CC window, to SCL rising edge
crossing 30% of V_CC.
From SCL falling edge crossing 30%
of V_CC to SDA entering the 30% to
70% of V_CC window.
From SCL rising edge crossing 70% of
V_CC, to SDA rising edge crossing 30%
of V_CC.
From SDA rising edge to SCL falling
edge. Both crossing 70% of V_CC.
From SCL falling edge crossing 30%
of V_CC, until SDA enters the 30% to
70% of V_CC window.
