The Ideality Configuration Registers store the ideality correction factor that is applied to each external
diode.
The table below shows the ideality factor settings for the Ideality Configuration registers. Shading
indicates power-up default. All codes that are not listed are reserved and should not be used.
Beta Compensation and Resistance Error Correction automatically correct for most diode ideality
errors, therefore it is not recommended that these settings be updated without consulting SMSC.
