Timings
Timing Diagram Conventions
This data sheet contains timing diagrams. The following key explains the components used in these diagrams. Any variations are
clearly labelled when they occur. Therefore, no additional meaning should be attached unless specifically stated.
Timing Conditions
Unless specified otherwise, the following conditions are true for all timing measurements. All characteristics are specified at
VDDIO = 3.1 - 3.5 V and VSS = 0 V over an operating temperature of -40C to +85C. Pin loadings is 50 pF. The timing values are
referenced to 1/2 VDD.
