System Power Management Status and Control 1 Register
(SPMSC1)
Low-Voltage Warning Flag — The LVWF bit indicates the low voltage warning status.
0 Low voltage warning is not present.
1 Low voltage warning is present or was present.
Low-Voltage Warning Acknowledge — The LVWF bit indicates the low voltage warning status.Writing a 1 to
LVWACK clears LVWF to a 0 if a low voltage warning is not present.
Low-Voltage Warning Interrupt Enable — This bit enables hardware interrupt requests for LVWF.
0 Hardware interrupt disabled (use polling).
1 Request a hardware interrupt when LVWF = 1.
Low-Voltage Detect Reset Enable — This write-once bit enables LVD events to generate a hardware reset
(provided LVDE = 1).
0 LVD events do not generate hardware resets.
1 Force an MCU reset when an enabled low-voltage detect event occurs.
Low-Voltage Detect Stop Enable — Provided LVDE = 1, this control bit determines whether the low-voltage
detect function operates when the MCU is in stop mode.
0 Low-voltage detect disabled during stop mode.
1 Low-voltage detect enabled during stop mode.
Low-Voltage Detect Enable — This write-once bit enables low-voltage detect logic and qualifies the operation
of other bits in this register.
0 LVD logic disabled.
1 LVD logic enabled.
Bandgap Buffer Enable — This bit enables an internal buffer for the bandgap voltage reference for use by the
ADC module on one of its internal channels or ACMP on its ACMP+ input.
0 Bandgap buffer disabled.
1 Bandgap buffer enabled.
