ADC calibration values

Hi all,

 

I'm using a K10 ADC in single ended mode, and trying to understand the calibration process. I have two main questions...

 

1. ADCx_CLPD, should this value be taken into account when generating ADCx_PG? The value seems to be generated during a self cal, but the documentation doesn't mention it.The K10 RM only says in 33.4.7..."2. Add the plus-side calibration results CLP0, CLP1, CLP2, CLP3, CLP4, and CLPS to the variable." So should CLPD also be added?

 

2. If storing calibration values in eeprom, so that calibration doesn't have to be re-done every boot, which registers need to be remembered? The documentation talks about 20 register stores, that makes me think its CLP0, 1, 2, 3, 4, CLPS, CLPD, OFFS, PG and MG for each ADC?

 

Thanks in advance,

Bill
