/* MAC internal memory addresses are 23 bit quantities.  The MAC uses
 * a paged address space where the upper 16 bits are the page number
 * and the lower 7 bits are the offset.  There are various Host API
 * elements that require two 16-bit quantities to specify a MAC
 * internal memory address.  Unfortunately, some of the API's use a
 * page/offset format where the offset value is JUST the lower seven
 * bits and the page is  the remaining 16 bits.  Some of the API's
 * assume that the 23 bit address has been split at the 16th bit.  We
 * refer to these two formats as AUX format and CMD format.  The
 * macros below help handle some of this.
