By default, the beta compensation circuitry is disabled and the EMC1053 is configured to measure
discrete diode-connected transistors. Writing to the Beta Configuration Registers will enable the beta
compensation circuitry and should be used if measuring a CPU substrate diode.
The beta compensation circuit is able to compensate for beta variation within a given range. The beta
configuration register is configured to the proper range to match the CPU to be monitored. The beta
values should be set so that the minimum expected beta is not below the threshold indicated in
Table 4.10. Beta compensation is activated if the BETA<2:0> bits are set to any value other than 07h.
