  Information Mailbox Pointer - 32bit RW
 ------------------------------------------
 This register holds the start address of
 the information mailbox located in the Wlan hardware memory.
 The host must read this pointer after a reset to find
 the location of the information mailbox.
 The Wlan hardware initializes the information mailbox pointer
 with the default address of the information mailbox.
 The information mailbox pointer is not valid
 until after the host receives the Init Complete interrupt from
 the Wlan hardware.
