: Timer 0 run control.
: External interrupt 1 flag.
: External interrupt 1 level/edge trigger control.
: External interrupt 0 flag.
: External interrupt 0 level/edge trigger control.
If IT1 = 0, cleared by S/W (software).
If IT1 = 1, cleared by H/W when the interrupt is serviced.
Edge detect (IT1=1) / Level detect (IT1=0; Default)
If IT0 = 0, cleared by S/W (software).
If IT0 = 1, cleared by H/W when the interrupt is serviced.
