1) Modules that are controllable by programming the register PMCON1.
2) Not subject to production test, verified by design/characterisation.
3) Baseload current is measured when the device is running in user mode with an endless loop in the flash
4) ADC active current is measured with: module enable, ADC analog clock at 8MHz, running in parallel
5) SSC active curremt is measured with: module enabled, running in loop back mode at a baud rate of 1 MBaud
6) CCU6 active current is measured with: module enabled, all timers running in 8 MHz, 6 PWM outputs are
7) Timer 2 active current is measured with: module enabled, timer running in 8 MHz
8) MDU active current is measured with: module enabled, division operation was performed.
