AT90SCR100 Boundary-scan Order

Table 27-1 shows the Scan order between TDI and TDO when the Boundary-scan chain is

selected as data path. Bit 0 is the LSB; the first bit scanned in, and the first bit scanned out. The

scan order follows the pin-out order as far as possible. Therefore, the bits of Port A and Port K is

scanned in the opposite bit order of the other ports. Exceptions from the rules are the Scan

chains for the analog circuits, which constitute the most significant bits of the scan chain regard-

less of which physical pin they are connected to. In Figure 27-3, PXn. Data corresponds to FF0,

PXn. Control corresponds to FF1, PXn. Bit 4, 5, 6 and 7 of Port F is not in the scan chain, since

these pins constitute the TAP pins when the JTAG is enabled.
