Register Map Summary
Control the MSL2100 using the registers in the range 0x00 through 0x57 (Table 3). Two additional registers, 0x90 and
0x91, allow access to, and programming of, the EEPROM. The power-up default values for all control registers are stored
within the on-chip EEPROM, and any of these EEPROM values may be changed through the serial interface.
