1
All Timing Specifications valid over VDD range of 3.0V to 3.6V and VDDIO range of 3.0V to 3.6V.
2
The timing parameters for SCLK, SDFS, SDO0, SDO1, and DR apply to both channels (0, 1)
3
Specification pertains to control signals: RW, (/WR), /DS, (/RD), /CS
4
(C
LOAD
=40pF on all outputs unless otherwise specified)
5
There is no hold time for SDA because as this waits for a negative transition (
↓
) on SCL to transition.
