Are there any other registers that need to be set?

Latest Updated:06/10/2013

Question:

Even though the low-voltage detection control register (LVDCR) has been set, low voltage detection is not occurring at the intended voltage. Are there any other registers that need to be set?

Answer:

Has 3Ch been set to the key code register for low-voltage detection control register (LVDKEYR) before writing to the LVDCR register? Writing of the LVDCR register is enabled/disabled by the LVDKEYR register. Write 3Ch to the LVDKEYR register and read LVDKEYR once, and then write to LVDCR.
