11.8 PSoC System Resources
Specifications are valid for –40 °C  T_A  85 °C and T_J  100 °C, except where noted. Specifications are valid for 1.71 V to 5.5 V,
except where noted.
11.8.1 POR with Brown Out
For brown out detect in regulated mode, V_DDD and V_DDA must be  2.0 V. Brown out detect is not available in externally regulated
mode.
