Memory Address Pointer (MAP)
Not a register
CS44800 I.D. and Revision Register (address 01h) (Read Only)
Increment (INCR)
Default = 1
Function:
memory address pointer auto increment control
Memory Address Pointer (MAPx)
Default = 0000001
Function:
Memory address pointer (MAP). Sets the register address that will be read or written by the control port.
Chip I.D. (Chip_IDx)
Default = 1100
Function:
Chip Revision (Rev_IDx)
Default = 0001
Function:
CS44800 revision level. Revision A is coded as 0001.
– 0 - MAP is not incremented automatically.
– 1 - Internal MAP is automatically incremented after each read or write.
