Notes:
1.
Not production tested (guaranteed by design).
2.
All timing references measured at VIL and VIH.
3.
The Si3452 will stretch (pull down on) SCK during the ACK time period if required. The maximum SCL stretching is
10 sec; so, SCL only needs to be bidirectional for I2C bus speeds over 50 kHz.
