19.3.1.6.3 Zero-Power BOR (ZPBOR)

The ZPBOR is a low-power BOR used during the Deep Sleep operation. The ZPBOR is enabled only when the CFGCON4.DSZPBOREN configuration bit is set as 1. See CFGCON4(L) from Related Links.

If ZPBOR is disabled, the internal circuitry does not perform power monitoring. When ZPBOR is enabled, the minimum operating voltage must remain above 2.1 V. If the operating voltage falls below 2.1 V, disable ZPBOR and use an external voltage monitoring solution, such as a voltage supervisor IC.
