External Diode Ideality Factor Registers 27h to 31h

These registers store the ideality factors that are applied to the external diodes. Table 6.18 defines

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.
