2N3904) or a CPU diode that functions like a discrete thermal diode (such as an AMD processor
diode), then the BETA[2:0] bits should be set to ‘111b’.
These registers store the ideality factors that are applied to the external diodes.
each setting and the corresponding ideality factor. 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.
