DLPC150: Question from DLPC150 Programmer’s Guide (Figure 2-10)

Hi Experts,

Good day.

User's Guide dlpu031a.pdf, on picture explaining 24-bit parallel port External triggering, there are only 23 trigger pulses and G0 is missing. While for internal 24-bit parallel port triggering, there are 24 pulses, all 24RGB bits + "Dark Count".

Can you explain the situation with external triggering - is it really only 23 pulses and G0 is supposed to be left out or is the datasheet misleading? I noticed, that even with external triggering there is one dark screen appearing after 24 pulses.

Thank you.
