SLOCK — Synthesizer Lock Flag
0 = VCO is enabled, but has not locked.
1 = VCO has locked on the desired frequency (or system clock is external).
The MCU maintains reset state until the synthesizer locks, but SLOCK does not indicate synthesizer
lock status until after the user writes to SYNCR.
RSTEN — Reset Enable
0 = Loss of crystal causes the MCU to operate in limp mode.
1 = Loss of crystal causes system reset.
STSCIM — Stop Mode System Integration Clock
0 = When LPSTOP is executed, the SCIM clock is driven from the crystal oscillator and the VCO is
turned off to conserve power.
1 = When LPSTOP is executed, the SCIM clock is driven from the VCO.
STEXT — Stop Mode External Clock
0 = When LPSTOP is executed, the CLKOUT signal is held negated to conserve power.
1 = When LPSTOP is executed, the CLKOUT signal is driven from the SCIM clock, as determined
by the state of the STSCIM bit.
3.4.4 Periodic Interrupt Timer
The periodic interrupt timer (PIT) generates interrupts of specified priorities at specified intervals. Timing
for the PIT is provided by a programmable prescaler driven by the system clock.
This register contains information concerning periodic interrupt priority and vectoring. Bits [10:0] can be
read or written at any time. Bits [15:11] are unimplemented and always return zero.
PIRQL[2:0] — Periodic Interrupt Request Level
The table below shows what interrupt request level is asserted when a periodic interrupt is generated.
If a PIT interrupt and an external IRQ of the same priority occur simultaneously, the PIT interrupt is ser-
viced first. The periodic timer continues to run when the interrupt is disabled.
PIV[7:0] — Periodic Interrupt Vector
The bits of this field contain the vector generated in response to an interrupt from the periodic timer.
When the SCIM responds, the periodic interrupt vector is placed on the bus.
