Register descriptions:
Status- Contains the results of calibrations, instructions and activity in the AMIS-53050.
Software State- Shows the current mode of the AMIS-53050.
Instruction Enable- Indicates that the AMIS-53050 is ready to receive a new instruction.
Busy- Indicates that the AMIS-53050 is still busy with internal tasks.
6.4.5.1. Status/Flag1
The purpose of the Status1 register is to provide information back to the host on the status of the part. This register should be queried
at the completion of calibration sequences to ensure proper operation. The flags will be reset when the register is read.
CheckSum indicates whether an attempt to read or write the EE has failed due to an incorrect CheckSum.
Instruction Enable indicates that the AMIS-53050 is ready to receive an instruction. This can be used to insure that the AMIS-53050
does not miss a command instruction due to the AMIS-53050 not being ready. Along with the busy flag, these status flags can police
the flow of commands to the AMIS-53050.
