Programmable Trigger Register Ready. If return to 1, the
software or firmware can write next event to trigger register. If
return to 0, the software or firmware cannot write trigger event
to event queue, that is, the timer is not timeout yet.
Speech Programmable Trigger Register. The software or
firmware can set these bits to trigger speech sound. The
vectors of sound trigger are shown as follows. If the bit of
trigger register ready is logic 0, this trigger register will be
ignored. Therefore, the bit of the trigger ready should be read
before programming this register.
Enable W83791SD/SG to program external serial flash
memory.
Enable Software/Firmware Trigger Timeout Function. This bit
sets the Event Trigger Timeout Function in Index 08h.
If read this bit return “1” means SPKOUT is in busy.
Write ‘0’ the EVNTRAP5-1 will positive edge trigger, Write ‘1’
will negative edge trigger. Default is ‘0’.
