CCS/TMS320C6727B: Assigning GPIO to EMIF Address lines using genBootCfg Utility

$

Part Number: TMS320C6727B

Tool/software: Code Composer Studio

This tool seems to have an issue with the EMIF Address pins. I am using the TQFP package. This device has BA[1:0] and address pins EM_A[12:0]. However the script is looking for the user to map EMIF address pins EM_A[24:12].  The upper address pins are not relevant in that I am using a 128Kx16 device that requires 17 address pins. 

Per the EMIF App note, I am mapping BA[1] to EMIF_A[0] and EM[12:0] to EMIF_A[13:1]. I planned to map the memory address pins [16:14] to GPIO pins.

When looking at the tool genBootCfg options for assigning EMIF address pins to GPIO, it allows for address pins from EMIF_A12 to EMIF_A24. The app note states that some devices do not provide an EMIF_A12 pin. I am assuming it is there for this scenario but assumed it would be "greyed" out like other options that are not available for this specific configuration.

I am just skipping assigning EMIF_A12 and hope that works. 

The SM320C6727B datasheet shows that this device provides a pin for EMIF_A12. Is this just a stale reference to older 6727 devices??
