ACCESS -- Register Access word
It is mandatory that the first 5 registers R0-R4 be programmed. The programming of registers R5-R7 is optional.
The ACCESS[3:0] bits determine which additional registers need to be programmed. Any one of these registers
can be individually programmed. According to the table below, when the state of a register is in default mode, all
the bits in that register are forced to a default state and it is not necessary to program this register. When the
register is programmable, it needs to be programmed through the MICROWIRE. Using this register access
technique, the programming required is reduced up to 50%.
