Electrical characteristics
The total current consumption is given by Equation 1:
Equation 1
I_DD = I_DD(Run2) + I_DD(ADC2) + I_DD(ACU) + I_DD(PLL) + I_DD(PWM)
where I_DD(PWM) = I_DD(PWM1) * N_PWM
More generally, the PWM current consumption has to be individually evaluated for each
f_SMED clock grouping, using Equation 2.
Equation 2
Nf_SMED
I_{DDPWM} = _{i = 1}XXXXI_{DDPWMi1}  N_i
where i = f_SMED clock group index; N_i = PWM number of the i_th clock group;
N_fSMED = f_SMED clock group number.
