Low Voltage Reset Flag — If low voltage reset feature is not available (see device specification) LVRF always
reads 0. LVRF is set to 1 when a low voltage reset occurs. This flag can only be cleared by writing a 1. Writing
a 0 has no effect.
0 Low voltage reset has not occurred.
1 Low voltage reset has occurred.
PLL Lock Interrupt Flag — LOCKIF is set to 1 when LOCK status bit changes. This flag can only be cleared
by writing a 1. Writing a 0 has no effect.If enabled (LOCKIE = 1), LOCKIF causes an interrupt request.
0 No change in LOCK bit.
1 LOCK bit has changed.
Lock Status Bit — LOCK reflects the current state of PLL lock condition. This bit is cleared in self clock mode.
Writes have no effect.
0 PLL VCO is not within the desired tolerance of the target frequency.
1 PLL VCO is within the desired tolerance of the target frequency.
Track Status Bit — TRACK reflects the current state of PLL track condition. This bit is cleared in self clock mode.
Writes have no effect.
0 Acquisition mode status.
1Tracking mode status.
Self Clock Mode Interrupt Flag — SCMIF is set to 1 when SCM status bit changes. This flag can only be
cleared by writing a 1. Writing a 0 has no effect. If enabled (SCMIE = 1), SCMIF causes an interrupt request.
0 No change in SCM bit.
1 SCM bit has changed.
Self Clock Mode Status Bit — SCM reflects the current clocking mode. Writes have no effect.
0 MCU is operating normally with OSCCLK available.
1 MCU is operating in self clock mode with OSCCLK in an unknown state. All clocks are derived from PLLCLK
running at its minimum frequency f
