TMS, I/O
The TMS pin controls the use of the IEEE 1149.1
Boundary Scan pins (TCK, TDI, TDO). In flexible mode
when the TMS pin is set LOW, the TCK, TDI and TDO pins
are boundary scan pins. Once the boundary scan pins are
in test mode, they will remain in that mode until the
internal boundary scan state machine reaches the "logic
reset" state. At this point, the boundary scan pins will be
released and will function as regular I/O pins. The "logic
reset" state is reached 5 TCK cycles after the TMS pin is
set HIGH. In dedicated test mode, TMS functions as
specified in the IEEE 1149.1 specifications. IEEE JTAG
specification recommends a 10kΩ pull-up resistor on the
pin. BST pins are only available in A42MX24 and
A42MX36 devices.

WD, I/O
When a wide decode module is used in a 42MX device
this pin can be used as a dedicated output from the wide
decode module. This direct connection eliminates
additional interconnect delays associated with regular
logic modules. To implement the direct I/O connection,
connect an output buffer of any type to the output of
the wide decode macro and place this output on one of
the reserved WD pins.
