+Description: 
+
+	This file contains the declaration of all functions exported from the 
+	APIMI block.  The APIMI block contains only one function:
+		Oct6100InterruptMask.
+	The function is used to mask out the interrupt pin of the chip.  This 
+	function is used when a deferred procedure call treats the interrupt (new 
+	interrupts must not be generated until the signalled interrupt is treated).

+Structure:		OCT6100_RPC_WRITE_BURST
+
+Description:    Command structure for a write burst.  The burst starts at the
+				given address and writes a given word for each address.
+
+				Whereas every command structure uses a complete dword for every
+				member, irrespective of the size of data unit needed, this
+				structure does not do so for the write data.  To save bandwidth
+				the write data words are sent two per dword.
+
+Example packet:	31                 16 15                  0
+				-------------------------------------------
+				|             ulAddress = 0x100           |
+				-------------------------------------------
+				|            ulBurstLength = 0x3          |
+				-------------------------------------------

+				-------------------------------------------
+				|         D2         |         xx         |
+				-------------------------------------------
+
+				Dy is the write data for ulAddress + 2 * y.
