Continued with my post yesterday, it appears I can read the first byte of data from the device...I think.  I have validated the part is talking as I changed the address and then didn't get the ACK back on the 9th clock, so that tells me I can address it, etc.

So I did a sequence of writing to the address pointer of 0x01 (config register) by sending a address with the lsb low for a write, then sending the pointer address and it appears I get the ACK back again.  So far so good.

I then send a read command...ie...address with R/W set high, and get the ack on the 9th clock as expected.  Then I set the RCEN bit, and loop

Pretty much what is here

I look at the data on the scope and it looks what I expect for the first byte of the config register of the part...BUT...it seems I only have 8 clocks coming out, not the 9 I expect, and it hangs at that point in the code.  SDA goes high and the SCL goes low.

Sorta stuck on why Im not getting the 9th clock.  Any thoughts folks?
