1 = Internal pullup is disconnected
0 = Internal pullup is connected between pin IRQ 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
Address:
The RSTEN bit is cleared by a power-on reset (POR) only. Other resets will
leave this bit unaffected.
