I'm having some issues with the initialization sequence.
Specifically, when I follow the recommended sequence that is
described in Table 32 (Page 48), I don't get the expected behavior. In
particular, at Step 28, I consistently read 0x99 instead of 0x09. Is
there a typo in the data sheet, or is there something truly wrong with the DAC
at that point?
Also, could you please explain the differences between the
status bits at address 0x21 (page 26)? They seem to be redundant.
Also, when I try to use the IRQ line from the DAC, I seem to be
unable to clear the interrupt conditions. In other words, writes to
address 0x03 don't seem to have any effect.
Thanks very much,
