(1) The current consumption of the brownout module is already included in the I_CC current consumption data. The voltage level V_{(B_IT–)} +
V_{hys(B_IT–)}is ≤ 1.8 V.
(2) During power up, the CPU begins code execution following a period of t_d(BOR) after V_CC = V_{(B_IT–)} + V_{hys(B_IT–)}. The default DCO settings
must not be changed until V_CC ≥ V_CC(min), where V_CC(min) is the minimum supply voltage for the desired operating frequency.
