31.1.3 Modes of Operation
The JTAG_EN pin can select between the following modes of operation:
31.2 External Signal Description
The JTAG module has five input and one output external signals, as described in
31.2.1 JTAG Enable (JTAG_EN)
The JTAG_EN pin selects between the Debug module and JTAG. If JTAG_EN is low, the Debug
module is selected; if it is high, the JTAG is selected.
selected depending upon JTAG_EN logic state.
When one module is selected, the inputs into the other module are disabled or forced to a known
logic level as shown in
