19.0 Test Features
The TAP controller contains a device ID register which holds
the device identification. Figure 24 shows the makeup of the
device ID register and the device ID value for the DS92UT16
device.
DEVICE ID = 0FC2801F
19.2 BOUNDARY SCAN
The DS92UT16 device contains boundary scan (BS) cells on
all inputs, outputs, bi-directs, and direction control signals.
There are no boundary scan cells on any of the inputs or
outputs from the pins to the LVDS Interface block. The
boundary scan order is shown in Table 95 along with the
type and controlling BS cell for bidirectional BS cells.For
bidirectional pins, if the controlling cell is a logic ‘1’ then they
are outputs.
