Hello,

Does Piccolo support JTAG daisy-chain ?
One of our customer wants to put 4 F28022s on one board.

Obata-san,

Daisy-chaining is possible. Since the JTAG pins are multiplexed with the GPIO function, caution has to be exercised to ensure the circuitry connected to the GPIO feature does not adversely affect other JTAG operations.
