On-chip peripheral current consumption
The current consumption of the on-chip peripherals is given in Table 32 . The MCU is placed
under the following conditions:

All I/O pins are in analog mode

All peripherals are disabled unless otherwise mentioned

The given value is calculated by measuring the current consumption
–
with all peripherals clocked off
– with only one peripheral clocked on

Ambient operating temperature and supply voltage conditions summarized in Table 18:
