If the user applicationinvolves on-board flash programming, this extra current must be taken into account while architecting the power-supply stage.(3)IDDA18includes current into VDD1A18and VDD2A18pins. In order to realize the IDDA18currents shown for IDLE, STANDBY, and HALT,clock to the ADC module must be turned off explicitly by writing to the PCLKCR0 register.(4)IDDA33includes current into VDDA2and VDDAIOpins.(5)The TYP numbers are applicable over room temperature and nominal voltage. MAX numbers are at 125°C, and MAX voltage (VDD=2.0 V; VDDIO, VDD3VFL, VDDA= 3.6 V).
