POR and LVD
17.2.2
The Voltage Monitor Comparators Register (VLT_CMP) is
used to read the state of internal supply voltage monitors.
Bit 3: NoWrite. This bit is only used in PSoC devices with a
2.4V minimum POR. It reads the state of the Flash write
voltage monitor.
Bit 1: LVD.
detect comparator. The trip point for the LVD is set by
VM[2:0] in the VLT_CR register.

Bit 0: PPOR. This bit reads back the state of the PPOR
output. This can only be meaningfully read with POR-
LEV[1:0] set to disable PPOR. In that case, the PPOR sta-
tus bit shows the comparator state directly.
