Table 49. Register 0x16 — EDO/Single Channel Enable (Note 1)

Bit

Name

R/W

Description

EDO_En1

R/W

Enable EDO on GPIO5. Default = 0.

EDO_En2

R/W

Enable EDO on GPIO6. Default = 0.

Single−Channel

Mode Select

R/W

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.

[7:3]

Channel Select

R/W

These bits are used to set the single channel that the ADT7462 measures in single−channel

mode.

0010 1 = +12V1

0011 0 = +12V2

0011 1 = +12V3

0100 0 = +3.3V

0100 1 = Pin 15 voltage

0101 0 = Pin 19 voltage

0101 1 = +5V

0110 0 = Pin 23 voltage

0110 1 = Pin 24 voltage

0111 0 = Pin 25 voltage

1000 0 = +1.5V1 (ICH) voltage

1000 1 = +1.5V2 (3GIO) voltage

Attenuator Pin 8

R/W

Setting this bit to 0 removes the attenuators for Pin 8. Default = 1 = attenuators enabled.

Attenuator Pin 13

R/W

Setting this bit to 0 removes the attenuators for Pin13. Default = 1 = attenuators enabled.

Attenuator Pin 15

R/W

Setting this bit to 0 removes the attenuators for Pin 15. Default = 1 = attenuators enabled.

Attenuator Pin 19

R/W

Setting this bit to 0 removes the attenuators for Pin 19. Default = 1 = attenuators enabled.

Attenuator Pin 21

R/W

Setting this bit to 0 removes the attenuators for Pin 21. Default = 1 = attenuators enabled.

Attenuator Pin 22

R/W

Setting this bit to 0 removes the attenuators for Pin 22. Default = 1 = attenuators enabled.
