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).

BATS Voltage High Condition Interrupt (BVHI)
To use the Voltage High Interrupt the Level Sensing must be enabled (BSESE =1 or BSUSE).
If measured when
a) V
HBI1
selected with BVHS = 0
at selected pin V
measure
V
HBI1_A
(rising edge) or V
measure
V
HBI1_D
(falling edge)
or when
a) V
HBI2
selected with BVHS = 1
at selected pin V
measure
V
HBI2_A
(rising edge) or V
measure
V
HBI2_D
(falling edge)
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).
