hi,
I am trying to find a few information on the data sheet and I cannot for FPGA coding. I need some technical support to verify this data sheet.
Some information are really confusing in the data sheet
thanks

Hi Hariharan,
Welcome to our e2e forum! What sort of information are you looking for with regards to the TLV2556?
Tom,
Thanks for your reply. Could you explain me more on your reply.
The four MSB's of the SDI are considered the address bits. You actually need to write to CFGR2 first (see Figs 1 and 2 and review the text on page 10). So writing 0xFx gets you to CFGR2, I understood here and no confusing
and you can setup the reference, pick EOC or INT. When I set up for EOC how do I configure default mode. What is this default mode means? My concern was this default mode set EOC or INT by default. The default mode is common for both CFGR2 and CFGR1.
The 'default' mode of CFGR1 is somewhat confusing since you have to write the full 8-bits for each command cycle. The four MSB's in this case would be 0x0 through 0xA to address each channel and the four LSB's would normally remain constant. The MSB 0x0 through 0xA addresses are taken for some other functions. It is described in the same page number. What is differentiate the address that is only used for CFGR1. When I set LSB 4 bits a constant value to what is configured. What is this constant value? Can I set any constant value?
Thanks
Hari
Hi Hari,
All addresses except 1111xxxxb can access the CFGR1 register. As far a a constant nibble to send, lets assume you want 12-bit reads, MSB first and unipolar binary representation of the conversion data - your input SDI would be 00000000b to get a conversion on channel 0. To get channel 10, with the same 12-bit, MSB first and uni-polar data, you write 10100000b to the device.
