The Beta Configuration Register controls advanced temperature measurement features of the External
Diode channels.
If External Diode 1 is selected as the hardware shutdown measurement channel (see
then the External Diode 1 Beta register will be read only. If the internal diode is selected, then this
register can be written normally. Likewise, if the External Diode 2 channel is selected (EMC2103-2
only) then this register can be written normally. Finally, if External Diode 2 is selected as the hardware
shutdown measurement channel (EMC2103-2 only), then the External Diode 2 Beta Configuration
Register will be read only.
