Hi!
I was wondering if anyone could confirm the following bits of the saa7134 irq registers, or point me to some technical info? The datasheet I found on Phillip's website doesn't seem to have this info.
Specifically I am interested in the interrupt enable bit for GPIO pin 16. Pins 18, 22, and 23 I reverse-engineered, but I can't work out what the GPIO16 interrupt enable bits are. I presume the reason why there are two enables is because they are rising/falling edge, but if GPIO16 is where I think it is then it only has one enable.
Also I would like confirmation of the report bit for GPIO16.
I'm hoping someone has this info already, otherwise I'll work this out manually.
Thanks,
- David.
