Configuration Register (CONFIG)
IRQPUD — IRQ Pin Pullup Control Bit
IRQEN — IRQ Pin Function Selection Bit
OSCENINSTOP— Oscillator Enable in Stop Mode Bit
RSTEN — RST Pin Function Selection
COPRS (Out of Stop Mode) — COP Reset Period Selection Bit
COPRS (In Stop Mode) — Auto Wakeup Period Selection Bit, depends on OSCSTOPEN in
CONFIG2 and external clock source
LVISTOP — LVI Enable in Stop Mode Bit
LVIRSTD — LVI Reset Disable Bit

OSCENINSTOP, when set, will allow the clock source to continue to generate clocks in stop mode.
This function can be used to keep the auto-wakeup running while the rest of the microcontroller stops.
When clear, the clock source is disabled when the microcontroller enters stop mode.
When the LVIPWRD bit is clear, setting the LVISTOP bit enables the LVI to operate during stop mode.
Reset clears LVISTOP.
LVIRSTD disables the reset signal from the LVI module.
1 = Internal pullup is disconnected
0 = Internal pullup is connected between IRQ pin and V
1 = Interrupt request function active in pin
0 = Interrupt request function inactive in pin
1 = Oscillator enabled to operate during stop mode
0 = Oscillator disabled during stop mode
1 = Reset function active in pin
0 = Reset function inactive in pin
1 = COP reset short cycle = 8176 × BUSCLKX4
0 = COP reset long cycle = 262,128 × BUSCLKX4
1 = Auto wakeup short cycle = 512 × (INTRCOSC or BUSCLKX2)
0 = Auto wakeup long cycle = 16,384 × (INTRCOSC or BUSCLKX2)
1 = LVI enabled during stop mode
0 = LVI disabled during stop mode
1 = LVI module resets disabled
0 = LVI module resets enabled

The RSTEN bit is cleared by a power-on reset (POR) only. Other resets will
leave this bit unaffected.
