|
|
* Some general notes:
|
|
*
|
|
* This file is basically a "what's new" header file. Since the
|
|
* BCM1250 and the new BCM1480 (and derivatives) share many common
|
|
* features, this file contains only what's new or changed from
|
|
* the 1250. (above, you can see that we include the 1250 symbols
|
|
* to get the base functionality).
|
|
*
|
|
* In software, be sure to use the correct symbols, particularly
|
|
* for blocks that are different between the two chip families.
|
|
* All BCM1480-specific symbols have _BCM1480_ in their names,
|
|
* and all BCM1250-specific and "base" functions that are common in
|
|
* both chips have no special names (this is for compatibility with
|
|
* older include files). Therefore, if you're working with the
|
|
* SCD, which is very different on each chip, A_SCD_xxx implies
|
|
* the BCM1250 version and A_BCM1480_SCD_xxx implies the BCM1480
|
|
* version.
