Data Sheet
6.9 EE
The AMIS-53000 uses internal EE memory to store register settings (either default factory settings or user defined settings).

6.9.1. Write EE
The serial interface provides a means to read and write the working registers of the AMIS-53000. To retain the information held by
these registers, on-board EE is provided to store all of the register contents needed for operation. The write EE command copies the
current contents of the working registers into EE, along with a CheckSum. The CheckSum is used to verify that the content of the EE is
valid when the EE is dumped back into the registers.
6.9.2. Load EE
The load EE command will refresh the contents of the working registers with the values stored in EE, if the EE CheckSum is valid. If
the EE CheckSum fails an error bit will be set in the Status2 register.
