REG_47VBOR33(1)VDDIO BOR (All modes)(1)1.7V
REG_48VBOR12BOR of the 1.2V regulator1.0V
REG_48AVZBPOR33Zero power BOR1.8V
REG_53TRST(2)External RESET valid active pulse width11µsMinimum Reset active time to guarantee module Reset. Reset filter circuit inside Module
REG_58BOR_DELAYWidth of the BOR event488µs
Note:
  1. VDD and VDDANA must be at the same voltage level.
  2. The RESET pulse width is the minimum pulse width required on the NMCLR pin after any filtering.
