(0, 0) Internal oscillator
(0, 1) External oscillator
(1, 0) External RC oscillator
(1, 1) External XTAL oscillator
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 = 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
0 = Auto wakeup long cycle = 16,384 × INTRCOSC
1 = LVI enabled during stop mode
0 = LVI disabled during stop mode
1 = LVI module resets disabled
0 = LVI module resets enabled
Address: $001F
The RSTEN bit is cleared by a power-on reset (POR) only. Other resets will
leave this bit unaffected.
