Boundary Scan Cell Functionality
The boundary scan cells implemented are analogous to cell BC_1, defined in the Standard
VHDL Package STD_1149_1_2001.
All boundary scan cells are of the type control-and-observe; they provide both controlla-
bility and observability for the pins to which they are connected. For open-drain outputs
and bidirectional pins, this type includes controllability and observability of output
enables.
Chain Sequence and Length
When enabled to shift data, the boundary scan shift register is connected to TDI at the
input line for TRIGOUT and to TDO at PD0. The shift register is arranged so that data is
shifted via the pins starting to the left of the OCI interface pins and proceeding clockwise
around the chip. If a pin features multiple scannable bits (example: bidirectional pins or
open-drain output pins), the data is shifted first into the input signal, then the output, then
the output enable (OEN).
The boundary scan register is 213 bits wide.
register, numbering them in clockwise order.
