hercules - EMIF port unused

Hi Jean-Baptiste,

If you configure the EMIF pins as 'EMIF' (in pinmux - for all multiplexed pins) then most of the pins will be OUTPUT and you don't need to worry about the output pins from a leakage standpoint. They should also be 'static' if you don't access EMIF or enable SDRAM - except for the EMIF_CLK pin. (EMI part of your question). You can see I / O / IO for each pin in section 17.2.3 EMIF Signal Descriptions - of the TRM.

The EMIF data bus which is IO would be your primary concern with respect to floating inputs - however the EMIF bus parking feature will prevent this. See section 17.2.7 Data Bus Parking.

EMIF wait input could be your other concern but it has a 20uA pullup (see datasheet section 4.3.2.15 External Memory Interface (EMIF))

EMIF clock can be disabled. There is a checkbox on the PINMUX -> Special Pin Muxing tab of HalCoGen. There is a bit field in the IOMM module that you can use to disable the clock (EMI reasons).
