Where, apart from section 5.6 of the ST40RA datasheet, is there any information about the EDQM pins and how to use them?

EDQM0 is not mentioned, except to say that for a peripheral, its function is "NOT_BE0" [whatever that means!? - perhaps "byte enable zero, active low" - just a guess].

The ST40RA datasheet refers to the "ST40 System Architecture Manual, Volume 2: Bus Interfaces" for more information on the EQDM pins, but I've looked through this document without success.

Can someone enlighten me on what these pins do and how to use them, please?
