Test Data Registers
As specified in the IEEE 1149.1 Standard, the
MT90840 JTAG interface contains two test data
registers:
The Boundary Scan Register consists of a
series of Boundary-Scan Cells arranged to form
a scan path around the boundary of the core
logic of the MT90840.
The Bypass Register is a single stage
shift-register that provides a one-bit path that
minimizes the distance for test data shifting
from the MT90840’s TDI to its TDO.
The MT90840 Boundary-Scan register contains 107
bits. The suffix (‘in’, ‘out’, or ‘en’) indicates the nature
and direction of the BSC. Bit 1 in Table 4 is the first
bit clocked out. All tristate enable bits are asserted
HIGH (i.e. a logic 1 enables the corresponding group
of output/bidirectional pins). Note that clocking all
zeros into the scan path register will set all outputs to
tristate (outputs disabled).
