HIGH DENSITY T1/E1 FRAMER
AND M13 MULTIPLEXER
Pin Name
Type Pin Function
No.
TMS
Input C2
Test Mode Select (TMS). This signal controls the test
operations that can be carried out using the IEEE
P1149.1 test access port. TMS is sampled on the
rising edge of TCK. TMS has an integral pull up
resistor.
TDI
Input C4
Output B3
Test Data Input (TDI). This signal carries test data into
the TECT3 via the IEEE P1149.1 test access port. TDI
is sampled on the rising edge of TCK. TDI has an
integral pull up resistor.
Test Data Output (TDO). This signal carries test data
out of the TECT3 via the IEEE P1149.1 test access
port. TDO is updated on the falling edge of TCK. TDO
is a tri-state output which is inactive except when
scanning of data is in progress.
TDO
TRSTB
Input B1
Active low Test Reset (TRSTB). This signal provides
an asynchronous TECT3 test access port reset via the
IEEE P1149.1 test access port. TRSTB is a Schmitt
triggered input with an integral pull up resistor. TRSTB
must be asserted during the power up sequence.
Note that if not used, TRSTB must be connected to the
RSTB input.
