Error Status Registers
Interpretation
Error Code 1 (16-bit)
Bit[0]: ‘1’
→
RESERVED
Bit[1]: ‘1’
→
Error in Calibration Data Capture The nature of data capture error is
indicated by using 3-bits in the 32-bit error code.
The value mappings are:
3
→
No Valid Capture
5
→
Poor SNR in signal
6
→
Signal Frequency is not fixed
Other Values are RESERVED
Bit[2]: ‘1’
→
Error in Input Signal Integrity. The nature of Input signal integrity error is
indicated by using 3-bits in the 32-bit error code. The value mappings are:
1
→
Signal power is low,
3
→
High spur in input signal,
4
→
Signal not in band,
Other Values are RESERVED
Bit[3]: ‘1’
→
Large Phase Error encountered across Codes.
Other bits are RESERVED
Error Code 2 (32-bit)
Bit[2:0]: Contains information about the first error condition in the above 16-bit
register. Example: Bit[1] of above register is set -> these 3-bits indicate the nature of
Data Capture error. If however, the data capture error is not set but the input signal
integrity error is set, then these bits correspond to input signal integrity error
Bit[5:3]: Contains information about the second error condition in the above 16-bit
register. Example: Bit[1] and Bit[2] of above register is set -> these 3-bits indicate the
nature of input signal integrity error
1.2.3.2
TX DSA Gain-Phase Factory Calibration Macro
This macro triggers the DSA gain phase calibration sequence for TX channels in AFE79xx. This should be
called after the system tune is done.
