Silicon Anomaly List
8.
17000043 - ADC Reference Voltages Do Not Match Specification:
DESCRIPTION:
The ADC reference voltages (VREF0, VREF1, and VREF2) are not calibrated to the specified 2.5 V.
WORKAROUND:
Use the actual ADC reference voltage values in ADC calculations, not the specified value.
APPLIES TO REVISION(S):
0.0
9.
17000044 - DAC Output Current Limit Is Less Than Specified:
DESCRIPTION:
The maximum DAC output current load specification is 5 mA. The actual DAC output current load is limited to 1 mA.
WORKAROUND:
None.
APPLIES TO REVISION(S):
0.0
10.
17000046 - ADC Auxiliary Bypass Mode Cannot Be Cleared By Register Write:
DESCRIPTION:
The auxiliary bypass bit cannot be cleared by a register write. If the ADC is set to enter auxiliary buffer bypass mode during operation, it
cannot subsequently be reverted to non-bypass mode.
WORKAROUND:
If the auxiliary bypass bit is set, a soft reset is required to take the AFE out of auxiliary buffer bypass mode. The ADCC drivers include the
adi_adcc_SetRegister() function to communicate with the AFE through the ADCC module. The ADCC drivers are furnished in the
EVAL-CM41X-EZBRD/EZLITE evaluation platform Board Support Package (BSP).
The following is an example to issue the soft reset to the Analog Front End:
#include <drivers/adcc/adi_adcc.h>
ADI_ADCC_HANDLE handle;
ADI_ADCC_RESULT result;
static char space[ADI_ADCC_MEMORY];
result = adi_adcc_Open(0, space, &handle, false);
result = adi_adcc_SetRegister(handle, REG_USER_CONFIG_REG0_USERCFG, 0x00400000);
if (result == ADI_ADCC_SUCCESS)
{
/* Success! */
}
else
{
/* Failure! */
}
For more information about the APIs, refer to Device Driver documentation and example codes in the Board Support Package (BSP).
APPLIES TO REVISION(S):
0.0
