I/O

FUNCTION

JTAG data input / Debug interrupt input

Run-time mode : input serial data to data/instruction register of JTAG.

I

Real-time mode : interrupt line to change the debug unit state from real time

mode to Run-time mode.

JTAG clock input

I The processor receives a serial clock on JTCK. On the rising edge of JTCK, both

JTDI and JTMS are sampled.

JTAG data output / PC Trace output

O Run-time mode : output serial data from data/instruction register of JTAG.

Real-time mode : output non-sequential program.

I

JTAG command

JTAG command signal, indicating the incoming serial data is command data.

Debug interrupt for EJTAG

I

Trigger output for EJTAG

O

JTAG Select

I

Test Reset input

I A reset input for a real-time debug system. When JTRST* is asserted, the debug

support unit (DSU) is initialized.
