X27A-G-006-02 Issue Date: 01/02/13
1.1 Conditions

Table 1-1: “S1D13705 Total Power Consumption” below gives an example of a specific

environment and its effects on power consumption.

Note

1. Conditions for Software Power Save:

• CPU interface active (signals toggling)

• CLKI active

2. Conditions for Hardware Power Save:

• CPU interface inactive (high impedance)

• CLKI active
