Enable EDO on GPIO5. Default = 0.
Enable EDO on GPIO6. Default = 0.
Setting this bit to 1 places the ADT7462 in single−channel mode. This means that it converts
on one channel only. The channel it converts on is set using the channel select bits in this re-
gister. Default = 0.
These bits are used to set the single channel that the ADT7462 measures in single−channel
mode.
Reserved for future use.
Setting this bit to 0 removes the attenuators for Pin 7. Default = 1 = attenuators enabled.
Setting this bit to 0 removes the attenuators for Pin 8. Default = 1 = attenuators enabled.
Setting this bit to 0 removes the attenuators for Pin13. Default = 1 = attenuators enabled.
Setting this bit to 0 removes the attenuators for Pin 15. Default = 1 = attenuators enabled.
Setting this bit to 0 removes the attenuators for Pin 19. Default = 1 = attenuators enabled.
Setting this bit to 0 removes the attenuators for Pin 21. Default = 1 = attenuators enabled.
Setting this bit to 0 removes the attenuators for Pin 22. Default = 1 = attenuators enabled.
