Table 13-2. Voltage Monitor Comparators Register (VLTCMP) [0x1E4] [R]
13.0.1 ECO Trim Register

Document 38-08035 Rev. *N
This read only register allows reading the current state of the Low-Voltage-Detection and Precision-Power-On-Reset compar-
ators
Bit [7:2]: Reserved
Bit 1: LVD
This bit is set to indicate that the low-voltage-detect comparator has tripped, indicating that the supply voltage has gone below
the trip point set by VM[2:0] (See
0 = No low-voltage-detect event
1 = A low-voltage-detect has tripped
Bit 0: PPOR
This bit is set to indicate that the precision-power-on-reset comparator has tripped, indicating that the supply voltage is below
the trip point set by PORLEV[1:0]
0 = No precision-power-on-reset event
1 = A precision-power-on-reset event has occurred
Note This register exists in the second bank of I/O space. This requires setting the XIO bit in the CPU flags register.
This register controls the ratios (in numbers of 32 kHz clock periods) of “on” time versus “off” time for LVD and POR detection
circuit.
Bit [7:6]: Sleep Duty Cycle [1:0]
0 0 = 1/128 periods of the Internal 32 kHz Low-speed Oscillator
0 1 = 1/512 periods of the Internal 32 kHz Low-speed Oscillator
1 0 = 1/32 periods of the Internal 32 kHz Low-speed Oscillator
1 1 = 1/8 periods of the Internal 32 kHz Low-speed Oscillator
Note This register exists in the second bank of I/O space. This requires setting the XIO bit in the CPU flags register.
