HI!
In my projiect I set the SDFM module of 28377D works at the mode0, 16bits ,filter3, osr256, EXT_RESET_DISABLE, only AE_ENABLE interrupt state. I find that the code of results rigester sometimes will go to the muximum (65535). At this time my input of sd-d is 0V, the correct code is 0, in the most time the code is right,but sometimes the code will go to the muximum.Why！
Hi! Manoj
Yes, it's my fault, I reading this register as unsigned integer.
The another question is about the SDDATA register.
In the datasheet of 28377, the description of SDDATA , The DATA16 represent the 16-bits data in 16b mode.
But in the sample programe of C:\ti\controlSUITE\device_support\F2837xD\v210\F2837xD_examples_Cpu1\sdfm_pwm_sync_cpu, the result is read like this. Filter1_Result[loopCounter1] = SDFM1_READ_FILTER1_DATA_16BIT; where the #define SDFM1_READ_FILTER1_DATA_16BIT *(Uint16 *)0x5E17.
So the SDFM1_READ_FILTER1_DATA_16BIT represent the Sdfm1Regs.SDDATA1.bit.DATA32HI. then I set the Filter1_Result[loopCounter1]=Sdfm1Regs.SDDATA1.bit.DATA32HI; the result is same as the Filter1_Result[loopCounter1] = SDFM1_READ_FILTER1_DATA_16BIT;
The description in the datasheet is error?
Shook,
I got your point. I shall be correcting this in next release of TRM. Here is the correct description:-
