13. Low Voltage Detect Control
Table 13-1. Low Voltage Control Register (LVDCR) [0x1E3] [R/W]
Document 38-08035 Rev. *N
This register controls the configuration of the Power on Reset/Low voltage Detection block.
Note This register exists in the second bank of IO space. This requires setting the XIO bit in the CPU flags register.
Bit [7:6]: Reserved
Bit [5:4]: PORLEV[1:0]
This field controls the level below which the precision power on reset (PPOR) detector generates a reset.
0 0 = 2.7V Range (trip near 2.6V)
0 1 = 3V Range (trip near 2.9V)
1 0 = 5V Range, >4.75V (trip near 4.65V). This setting must be used when operating the CPU above 12 MHz.
1 1 = PPOR does not generate a reset, but values read from the Voltage Monitor Comparators Register
internal PPOR comparator state with trip point set to the 3V range setting.
