DS110DF410: Register programming issue

Penn Zhang

Part Number: DS110DF410

Hello,

The channel register and shared register use the same address, I need to change the global register to choose which register can be changed, am I right?

But I find I set the global register to 0x05, 0x03, then it could be read back as 0x05 and 0x03, when I write global register to 0x07, then read back it is 0xa5? could you give me some suggestions on this? thanks.

Hi Rodrigo,

Thanks, 2 questions as below,

1. Sigcon GUI as below, the mask value for global register is FF, but in the programming guide, the mask value for global register is 0C, which is right? If I want to use GUI to write global register should I change the Mask Value to 0C?

2. As programming guide said, I should use the function 5 as below to calculate the final write value, then write this final write value to the register which wants to be written, am I right?
