Power Scaling 1
The values in Table 34-7 are measured values of power consumption under the following condi-
tions, except where noted:
• Operating conditions for power scaling mode 1
– V_VDDIN = 3.3V
• Wake up time from low power modes is measured from the edge of the wakeup signal to the
first instruction fetched in flash.
• Oscillators
– OSC0 (crystal oscillator) and OSC32K (32kHz crystal oscillator) stopped
– RCFAST Running at 12MHz
• Clocks
– RCFAST used as main clock source
– CPU, AHB clocks undivided
– APBC and APBD clocks divided by 4
– APBA and APBB bridges off
– The following peripheral clocks running
• PM, SCIF, AST, FLASHCALW, APBC and APBD bridges
– All other peripheral clocks stopped
