PROGRAMMING INFORMATION
3.1
REGISTER LIST AND MAP
There are 23 primary registers (including an Address Pointer Control
Register and 16 expanded registers in the device).
Whatever the control interface is, 5 address bits are used to set the
registers. In non-multiplexed parallel interface mode, the five dedicated
address bits are A[4:0]. In multiplexed parallel interface mode, AD[4:0]
carries the address information. In serial interface mode, A[5:1] are used
to address the register.
The Register ADDP, addressed as 11111 or 1F Hex, switches
between primary registers bank and expanded registers bank.
By setting the register ADDP to ‘AAH’, the 5 address bits point to the
expanded register bank, that is, the expanded registers are available. By
clearing register ADDP, the primary registers are available.
Primary Registers, whose addresses are 16H to 1EH, are reserved.
Expanded registers, whose addresses are 10H to 1EH, are used for test
and must be set to ‘0’ (default).
