rw
rwh External interrupt 0 request flag
rw
rwh External interrupt 1 request flag
External interrupt 0 level/edge trigger control
flag
If IT0 = 0, low level triggered external interrupt 0 is
selected.
If IT0 = 1, falling edge triggered external interrupt 0
is selected.
Set by hardware when external interrupt 0 edge is
detected. Cleared by hardware when processor
vectors to interrupt routine.
External interrupt 1 level/edge trigger control
flag
If IT1 = 0, low level triggered external interrupt 1 is
selected.
If IT1 = 1, falling edge triggered external interrupt 1
is selected.
Set by hardware when external interrupt 1 edge is
detected. Cleared by hardware when processor
vectors to interrupt routine.
