SONET/SDH TRIBUTARY UNIT PAYLOAD PROCESSOR FOR 622 MBIT/S
INTERFACES
Pin Name
Type
Pin
No.
Function
INTB
OD
Output
C14 The active low interrupt (INTB) signal goes low
when a TUPP+622 interrupt source is active.
INTB returns high when the interrupt is
acknowledged via an appropriate register
access. INTB is an open drain output.
TCK
TMS
Input
Input
C5
C4
The test clock (TCK) signal provides timing for
test operations that can be carried out using the
IEEE P1149.1 test access port. TCK has an
integral pull up resistor.
The test mode select (TMS) 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
B4
The test data input (TDI) signal carries test data
into the device via the IEEE P1149.1 test access
port. TDI is sampled on the rising edge of TCK.
TDI has an integral pull up resistor.
TDO
Tristat A3
e
The test data output (TDO) signal carries test
data out of the device via the IEEE P1149.1 test
access port. TDO is updated on the falling edge
of TCK. TDO is a tristate output that is always
tristated except when scanning of data is in
progress.
TRSTB
Input
D5
The active low test reset (TRSTB) signal
provides an asynchronous test access port
reset. TRSTB is a Schmitt triggered input with
an integral pull up resistor. TRSTB must be
asserted during the power up sequence.
