Interrupt flag BVLIF can only be cleared by writing a 1. If the interrupt is enabled by bit BVLIE the
module requests an interrupt to MCU (BATI).
16.4.2.2
To use the Voltage High Interrupt the Level Sensing must be enabled (BSESE =1 or BSUSE).
If measured when
or when
then BVHC is set. BVHC status bit indicates that a high voltage at the selected pin is present. The High
Voltage Interrupt flag (BVHIF) is set to 1 when a Voltage High Condition (BVHC) changes state. The
Interrupt flag BVHIF can only be cleared by writing a 1. If the interrupt is enabled by bit BVHIE the
module requests an interrupt to MCU (BATI).
