(1)

The current consumption of the brownout module is already included in the ICC current consumption data. The voltage level V(B_IT-) +

Vhys(B_IT-)is ≤ 1.8 V.

(2)

During power up, the CPU begins code execution following a period of td(BOR) after VCC = V(B_IT-) + Vhys(B_IT-). The default DCO settings

must not be changed until VCC ≥ VCC(min), where VCC(min) is the minimum supply voltage for the desired operating frequency.
