Description
I10
Interrupt indicating that input I10 has become valid
(if it was invalid), or invalid (if it was valid). Latched
until reset by software writing a 1 to this bit.
I9
Interrupt indicating that input I9 has become valid (if
it was invalid), or invalid (if it was valid). Latched
until reset by software writing a 1 to this bit.
