[Question]
There is no DBGRQ or DBGACK pin on the connected MPU. What should I do with the DBGRQ pin and DBGACK pin on the ICE interface connector?
[Answer]
Leave it as NC.
DBGRQ pin is an output signal from ICE.
DBGACK pin is an input signal to ICE, but 1kΩ pull-down resistor is provided within ICE internal circuit.
