ATmega169 Boundary-
scan Order
246
ATmega169V/L
Table 107 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 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 regardless of which physical pin they are connected to. In Figure
108, PXn. Data corresponds to FF0, PXn. Control corresponds to FF1, and PXn. Pull-
up_enable corresponds to FF2. Bit 2, 3, 4, and 5 of Port C is not in the scan chain, since
these pins constitute the TAP pins when the JTAG is enabled.
