Hello,Figure 5-29. Electrical Parameter Measurement Circuit
mark 20k resistance,Does it refer to the resistance of RSET to ground or the resistance connected in series with VSET PIN?

Thanks for your reply!
Hello,According to the suggestion:"datasheet 19 page “The VSET voltage is applied using a DAC through a 20kΩ series resistor.",
Setting conditions:
single-ended input;DC bias 2V/AVDD 3.3V OR 3V/AVDD 5V
(PD = 0);(MODE = 1);(RBIAS=1);High-Current Mode
The iout current is locked and cannot be controlled by VSET,VSET'' voltage is locked 3.7V
OR(PD = 0);(MODE = 0);(RBIAS=1);Low-Current Mode
The iout current is also locked and cannot be controlled by VSET,VSET'' voltage is locked 2.1V
Is there a problem with the circuit wiring method or design parameters, or is the development board damaged?
