4.6.2
Interrupt Sources
4.6.2.1
Voltage Status Interrupt (VSI)
The Voltage Status Interrupt - VSI combines the five interrupt sources of the Voltage Status Register. It is only available in the
Interrupt Source Register (ISR). Acknowledge the interrupt by reading the Voltage Status Register - VSR. To issue a new
interrupt, the condition has to vanish and occur again. See Section 4.4, “Power Supply" for details on the Voltage Status Register
including masking information.
4.6.2.2
Low Voltage Interrupt (LVI)
Acknowledge the interrupt by reading the Voltage Status Register - VSR. To issue a new interrupt, the condition has to vanish
and occur again. See Section 4.4, “Power Supply" for details on the Voltage Status Register including masking information.
4.6.2.3
Voltage Regulator High Temperature Interrupt (HTI)
Acknowledge the interrupt by reading the Voltage Status Register - VSR. To issue a new interrupt, the condition has to vanish
and occur again. See Section 4.4, “Power Supply" for details on the Voltage Status Register including masking information.
4.6.2.4
Low Battery Interrupt (LBI)
Acknowledge the interrupt by reading the Voltage Status Register - VSR. To issue a new interrupt, the condition has to vanish
and occur again. See Section 4.4, “Power Supply" for details on the Voltage Status Register including masking information.
4.6.2.5
TIM Channel 0 Interrupt (CH0)
See Section 4.18, “Basic Timer Module - TIM (TIM16B4C)".
