Boundary Scan Test Data Output. During
normal operation, the output TDO can be left
open.
Boundary Scan Test Mode Select Input,
internal pull-up.
Boundary Scan Test Reset. There is an
internal pull-up device implemented. TRST is
low active, which means the boundary scan
tap controller resets while TRST = ’0’.
For normal operation,
• TRST can be connected to a LOW signal
• TRST can be left open. In this case, the
In boundary scan test mode, TRST can be left
open, since the internal pull-up device pro-
vides the necessary HIGH signal.
Test Mode Enable Pin.
HIGH signal enables the chip internal test
mode.
Note: In normal operation, TEST must be
In OCDS mode, a falling edge from HIGH to
LOW signal on brkin forces the system to stop.
An internal pull-up resistor is provided.
In OCDS mode, a falling edge on brkout
indicates the trigger of a pre-selected OCDS
event.
