Description

IWUF register

Fields

IWUF0

IWUF0: Internal wakeup flag (LPUART).

  • 0: no wakeup from LPUART occurred since last clear.
  • 1: a wakeup from LPUART occurred since last clear. Cleared by writing 1 in this bit.
IWUF1

IWUF1: Internal wakeup flag (RTC).

  • 0: no wakeup from RTC occurred since last clear.
  • 1: a wakeup from RTC occurred
IWUF2

IWUF2: Internal wakeup flag (LCD).

  • 0: no wakeup from LCD occurred since last clear.
  • 1: a wakeup from LCD occurred since last clear. Cleared by writing 1 in this bit.
IWUF3

IWUF3: Internal wakeup flag (COMP).

  • 0: no wakeup from COMP occurred since last clear.
  • 1: a wakeup from COMP occurred since last clear. Cleared by writing 1 in this bit.
IWUF4

IWUF4: Internal wakeup flag (LCSC).

  • 0: no wakeup from LCSC occurred since last clear.
  • 1: a wakeup from LCSC occurred since last clear. Cleared by writing 1 in this bit.
WMRSUBGF

WMRSUBGF Wakeup MRSUBG Flag This bit is set by hardware when a MRSUBG wakeup is detected It is cleared by a reset pad or by software writing 1 in this bit field.

  • 0: No MRSUBG Wakeup detected
  • 1: MRSUBG Wakeup detected writting 1 in this bit, clears the interrupt
WMRSUBGHCPUF

WMRSUBGHCPUF Wakeup MRSUBG HOST CPU Flag (cf. user manual) This bit is set by hardware when a MRSUBG HOST CPU wakeup is detected It is cleared by a reset pad or by software writing 1 in this bit field.

  • 0: No MRSUBG Host CPU wakeup detected
  • 1: MRSUBG Host CPU wakeup detected writting 1 in this bit, clears the interrupt
WLPAWURF

WLPAWURF Wakeup LPAWUR Flag (cf. user manual) This bit is set by hardware when a LPAWUR wakeup is detected It is cleared by a reset pad or by software writing 1 in this bit field.

  • 0: No LPAWUR wakeup detected
  • 1: LPAWUR wakeup detected writting 1 in this bit, clears the interrupt
