Trigger delay
The cameras feature various ways to delay image capture based on external trig-
ger.
With IIDC V1.31 there is a standard CSR at register F0F00534/834h to control a
delay up to FFFh x timebase value. The following table explains the Inquiry reg-
ister and the meaning of the various bits.
Note

Make sure that output and input are not enabled at the same
time. In order to use a pin as an input (e.g. for external trig-
ger), its output driver (e.g. IntEna) needs to be switched off.
