Note: SRAM defaults are power-on defaults. EEPROM defaults are factory defaults.
Register Map
A description of the registers is below. The registers
are read only (R) or read/write (R/W). The R/W registers
are writable only if write protect has not been asserted
(see the Memory Description section).
Bytes designated as "Reserved" have been set aside
for added functionality in future revisions of this device.
