COMP2 DELAY FUNCTION
COMP2 has an optional delay function for use when the input signal is noisy. When COMP2 triggers
and the delay is enabled (i.e. COMP2DEL is non-zero), then GPIO bit 14 does not change state
immediately, and no interrupt is generated. Instead, the WM9713L starts a delay timer and checks
COMP2 again after the delay time has passed. If COMP2 is still active, then the GPIO bit is set and
an interrupt may be generated (depending on the state of the GW14 bit). If COMP2 is no longer
active, the GPIO bit is not set, i.e. all register bits are as if COMP2 had never triggered.
