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 pinout order as far as possible. Therefore, the bits of Port A and Port E 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
PXn. Control corresponds to FF1, and PXn. Pullup_enable corresponds to FF2. Bit 4, 5, 6, and
7of Port C is not in the scan chain, since these pins constitute the TAP pins when the JTAG is
enabled.
