2514H–AVR–05/03
The recommended values from Table 105 are used unless other values are given in the
algorithm in Table 106. Only the DAC and port pin values of the Scan Chain are shown.
The column “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 106. Algorithm for Using the ADC
Using this algorithm, the timing constraint on the HOLD signal constrains the TCK clock
frequency. 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,
