13.6 LVI Interrupts
The LVI module does not generate interrupt requests.
13.7 Low-Power Modes
The WAIT instruction puts the MCU in low-power-consumption standby
mode.
13.7.1 WAIT Mode
When the LVIPWR mask option is programmed to â1â, the LVI module is
active after a WAIT instruction.
When the LVIRST mask option is programmed to â1â, the LVI module can
generate a reset and bring the MCU out of WAIT mode.
