As an example, consider the task of verifying a 1.5V ±5% input signal at ADC channel 3 when
the power supply is 5.0V and AREF is externally connected to V

“Actions” describes what JTAG instruction to be used before filling the Boundary-scan Register
with the succeeding columns. The verification should be done on the data scanned out when
scanning in the data on the same row in the table.
Table 93. Algorithm for Using the ADC
Using this algorithm, the timing constraint on the HOLD signal constrains the TCK clock fre-
quency. As the algorithm keeps HOLD high for five steps, the TCK clock frequency has to be at
least five times the number of scan bits divided by the maximum hold time, t

result.
The DAC values must be stable at the midpoint value 0x200 when having the HOLD signal
