17000077 - FOCP Over Voltage and Under Voltage DAC Output Limited by Offset and Gain Errors:
DESCRIPTION:
The following errors limit the output of the Fast Over Current Protection (FOCP) Under Voltage (UV)/Over Voltage (OV) DACs:
• OV/UV DAC offset error (OFFSET_ERROR): 40+8 mV
• OV/UV full scale error (FULLSCALE_ERROR): -5+1 mV
• Gain error (GAIN_ERROR = FULLSCALE_ERROR - OFFSET_ERROR): -45+9 mV
WORKAROUND:
Set the input to the 8-bit OV and UV DACs based on the following equation:
OV/UV DAC_OUTPUT = OFFSET_ERROR + (DAC_INPUT/256)*(3.0 + GAIN_ERROR)
In the above equation, DAC_INPUT is the 8-bit digital input to the OV/UV DAC from the DAC controller, and DAC_OUTPUT is the analog
output from the OV/UV DAC.
APPLIES TO REVISION(S):
0.0

17000080 - Logic Block Array (LBA) Combinatorial Mode Is Not Functional:
DESCRIPTION:
The SYSBLK0_ENG_MODE_CFG0.LBA_COMB_MODE bit is used to enable the LBA combinatorial mode. This bit is not functional.
WORKAROUND:
None.
APPLIES TO REVISION(S):
0.0
26.
17000082 - Primary ADC Gain Error Correction Is Not Functional:
DESCRIPTION:
Primary ADC (ADC1 and ADC2) gain error correction is not functional. This feature is disabled. The primary ADC gain error is between -3%
to -5%.
The ADC input voltage is less than the full scale voltage of 3 V. It varies from device to device. It also varies between the three primary ADC
Muxes within a device.
WORKAROUND:
Calibrate the gain error for each device on the primary ADC Muxes (ADC1 MUX A, ADC1 MUX B, ADC1 MUX C, ADC2 MUX A, ADC2 MUX B,
and ADC2 MUX C) through software, if required.
APPLIES TO REVISION(S):
C
27.
17000083 - Floating Point Saturation Unit Is Not Functional:
DESCRIPTION:
The Floating Point Saturation (FSAT) unit is used to implement a 32-bit floating point saturation. This unit is not functional.
WORKAROUND:
None.
APPLIES TO REVISION(S):
