      The bandgap which supplies all POKs is within the POR. The bandgap generates an untrimmed voltage /
      current after MCU_PORz is released. In order to apply the device-specific trim to the bandgap, the user
      must set CTRL_MMR_POR_CTRL[7]. TRIM_SEL. The bandgap requires a 100us settling time (during which
      POK / PRG configuration may occur).
      • The device-specific bandgap trim is stored in CTRL_MMR_POR_BANDGAP_CTRL and it is recommended
      to not modify this trim value.
