(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.
