* LVIDR, LVI5OR3, URSTD, and LVID bits are reset by POR (power-on reset) or LVI reset only.
Address:
Reset:
The low V
LVI reset when the V
LVI circuit can be disabled by the setting the LVIDR bit in CONFIG.
There is no LVI circuit for V
Three bits in the configuration register (CONFIG) control the operation
of the LVI module.
LVIDR — LVI Disable Bit for V
LVI5OR3 — LVI Trip Point Voltage Select Bit for V
LVID — LVI Disable Bit for V
Read:
Write:
LVIDR disables the LVI circuit for V
LVI5OR3 selects the trip point voltage of the LVI circuit for V
Section 20. Electrical Specifications
LVID disables the LVI circuit for V
1 = LVI circuit for V
0 = LVI circuit for V
1 = LVI trips at 3.3V
0 = LVI trips at 2.4V
1 = LVI circuit for V
0 = LVI circuit for V
