TRPSEL — LVI Trip Select Bit
If LVIPWR and LVIRST are at logic 1, note that when changing the
tolerance, LVI reset will be generated if the supply voltage is below the
trip point.
The LVI module does not generate interrupt requests.
The WAIT instruction puts the microcontroller unit (MCU) in low
power-consumption standby mode.
With the LVIPWR bit in the configuration register programmed to logic 1,
the LVI module is active after a WAIT instruction.
With the LVIRST bit in the configuration register programmed to logic 1,
the LVI module can generate a reset and bring the MCU out of wait
mode.
The STOP instruction puts the MCU in low power-consumption standby
mode.
LVHX
This bit selects the LVI trip point. Reset clears this bit.
1 = 5 percent tolerance. The trip point and recovery point are
0 = 10 percent tolerance. The trip point and recovery point are
