Data based on a differential I
DD
measurement between reset configuration and timer counter running
at 16 MHz. No IC/OC programmed (no I/O pads toggling). Not tested in production.
(2)
Data based on a differential I
DD
measurement between the on-chip peripheral when kept under reset
and not clocked and the on-chip peripheral when clocked and not kept under reset. No I/O pads toggling.
Not tested in production.
(3)
Data based on a differential I
DD
measurement between reset configuration and continuous A/D
conversions. Not tested in production.
