But datasheet doesnt tells about the sign bit. RTFM erik malund the ‘header’ say so, but I can find nodocumentation in the datasheet proper. Doesn’t that answer the question?

I think I am correct. I went through the manual, it says in the differential mode it will work as datashdet bit ADC. If you got an idea please inform me. Neil Posted 4-Jul Thanks once again Andy and Eric for spending your valuable time in helping me. Read-Only Author erik malund Posted 5-Jul Thanks for quick reply. Example codes are shown below Replied Jun 153: What is the relation to from linear address to device address? Once again thanking you all. Please let us know if you have any additional question.
You showed me the correct page. Still going datasheett the manual. I am unable to get a solution what will be the output if the differential voltage is negative, since in my application both positive and negative voltage may come in the input. The following is a flash write function from the drivers.

The data is in 2’s complement. The 16th bit will be used for the sign bit. I will now try with what Eric says using the debugger. Neil “The 16th bit will be used for the sign bit. Please clear my doubt or tell me the link to the data sheet you are referring. So I think the 16th bit will be used as the sign bit. Thank you for your help.
Pg of the datasheet states the SFLE bit must be set to write to the scratchpad memory. It looks this is confusing. Replied Jun 152: Thank You in advance. After setting the c80051f060, you can use 16bit address as an input.
Community 8-bit MCU Forum. We cant measure negative voltage in single ended mode. But I am talking about 16 bit ADC in differential mode.

What would I have to do to “decode” the linear address to obtain the device address, as the function description implies? If you have not I suggest you take a look at the AN document and the example code. Please give suggestion if I am wrong. How am I supposed to write to an address within the scratchpad memory when the input to the write function is of type UINT, which means I can only go as high as 0xFFFF, range from 0 to ?
c8051f60 Replied Jun 193: Neil Doesn’t the Datasheet tell you this? Read-Only Author erik malund Posted 3-Jul Neil Posted 2-Jul Neil Do you understand the difference between having a sign bit plus 15 magnitude bits, and having a bit 2’s complement value? But we cant use them independantly in differential mode. Thanks for your help.
