8 Registers

8.1 Register Mapping

The S1D13504 registers are all memory mapped. The system must provide the external address decoding through the CS# and M/R# input pins. When CS# = 0 and M/R# = 0, the registers are mapped by address bits AB[5:0], e.g. REG[00h] is mapped to AB[5:0] = 000000, REG[01h] is mapped to AB[5:0] = 000001. See the table below:

8.2 Register Descriptions

Note

Unless specified otherwise, all register bits are reset to 0 during power up. Reserved bits should be written 0 when programming unless otherwise noted.
