Bit 11 – DPLLLDRTO DPLL Loop Divider Ratio Update Complete

This flag is cleared by writing '1' to it.

This flag is set on 0-to-1 transition of the DPLL Loop Divider Ratio Update Complete bit in the Status register (STATUS.DPLLLDRTO) and will generate an interrupt request if INTENSET.DPLLLDRTO is '1'.

Writing '0' to this bit has no effect.

Writing '1' to this bit clears the DPLL Loop Divider Ratio Update Complete interrupt flag.

Bit 10 – DPLLLTO DPLL Lock Timeout

This flag is cleared by writing '1' to it.

This flag is set on 0-to-1 transition of the DPLL Lock Timeout bit in the Status register (STATUS.DPLLLTO) and will generate an interrupt request if INTENSET.DPLLLTO is '1'.

Writing '0' to this bit has no effect.

Writing '1' to this bit clears the DPLL Lock Timeout interrupt flag.

Bit 9 – DPLLLCKF DPLL Lock Fall

This flag is cleared by writing '1' to it.

This flag is set on 0-to-1 transition of the DPLL Lock Fall bit in the Status register (STATUS.DPLLLCKF) and will generate an interrupt request if INTENSET.DPLLLCKF is '1'.

Writing '0' to this bit has no effect.

Writing '1' to this bit clears the DPLL Lock Fall interrupt flag.

Bit 8 – DPLLLCKR DPLL Lock Rise

This flag is cleared by writing '1' to it.

This flag is set on 0-to-1 transition of the DPLL Lock Rise bit in the Status register (STATUS.DPLLLCKR) and will generate an interrupt request if INTENSET.DPLLLCKR is '1'.

Writing '0' to this bit has no effect.

Writing '1' to this bit clears the DPLL Lock Rise interrupt flag.

This flag is cleared by writing '1' to it.

This flag is set on 0-to-1 transition of the OSC48M Ready bit in the Status register (STATUS.OSC48MRDY) and will generate an interrupt request if INTENSET.OSC48MRDY is '1'.

Writing '0' to this bit has no effect.

Writing '1' to this bit clears the OSC48M Ready interrupt flag.

Bit 1 – CLKFAIL XOSC Failure Detection

This flag is cleared by writing '1' to it.

This flag is set on a 0-to-1 transition of the XOSC Clock Failure bit in the Status register (STATUS.CLKFAIL) and will generate an interrupt request if INTENSET.CLKFAIL is '1'.

Writing '0' to this bit has no effect.

Writing '1' to this bit clears the XOSC Clock Fail interrupt flag.

Bit 0 – XOSCRDY XOSC Ready

This flag is cleared by writing '1' to it.

This flag is set on a 0-to-1 transition of the XOSC Ready bit in the Status register (STATUS.XOSCRDY) and will generate an interrupt request if INTENSET.XOSCRDY is '1'.

Writing '0' to this bit has no effect.

Writing '1' to this bit clears the XOSC Ready interrupt flag.
