"signal" and "interrupt" are just two different function attributes used
to denote a function as an interrupt handler. With the "interrupt"
attribute the handler will run with interrupts enabled. With the
"signal" attribute, the handler will run with interrupts disabled.
Otherwise, "signal" and "interrupt" mean exactly the same thing.
