Memory Address Pointer (MAP)
Not a register
Chip I.D. and Revision Register (Address 01h) (Read Only)
Increment (INCR)
Default = 1
Function:
Memory address pointer auto increment control
0 - MAP is not incremented automatically.
1 - Internal MAP is automatically incremented after each read or write.
Memory Address Pointer (MAP[6:0])
Default = 0000001
Function:
Memory address pointer (MAP). Sets the register address that will be read or written by the control port.
