ADM1029

GPIO REGISTERS

Bit

Name

R/W

Description

GPIO 0 = 1 (Pin 19)

This bit set to 1 means the ADM1029 can support GPIO0, available on Pin 19.

GPIO 1 = 1 (Pin 20)

This bit set to 1 means the ADM1029 can support GPIO1, available on Pin 20.

GPIO 2 = 1 (Pin 11)

This bit set to 1 means the ADM1029 can support GPIO2, available on Pin 11.

GPIO 3 = 1 (Pin 13)

This bit set to 1 means the ADM1029 can support GPIO3, available on Pin 13.

GPIO 4 = 1 (Pin 14)

This bit set to 1 means the ADM1029 can support GPIO4, available on Pin 14.

GPIO 5 = 1 (Pin 16)

This bit set to 1 means the ADM1029 can support GPIO5, available on Pin 16.

GPIO 6 = 1 (Pin 17)

This bit set to 1 means the ADM1029 can support GPIO6, available on Pin 17.

Reserved

Unused. Will read back 0.

Bit

Name

R/W

Description

GPIO 0 = 1

R/W

Indicates that GPIO0 is being used. Set to 1 on power-up, but can be over-

written by software. Setting this bit to 0 means AIN0 is being used.

GPIO 1 = 1

R/W

Indicates that GPIO1 is being used. Set to 1 on power-up, but can be over-

written by software. Setting this bit to 0 means AIN1 is being used.

GPIO 2 = 1

R/W

Indicates that GPIO2 is being used. Set to 1 on power-up, but can be over-

written by software.

GPIO 3 = ?

R/W

Indicates that GPIO3 is being used. Setting this bit to 0 means TDM1 is

being used. The ADM1029 can detect on power-up if TDM1 is connected. If

so then this bit is set to 0, otherwise it is set to 1. The default setting can be

overwritten by software.

GPIO 4 = ?

R/W

Indicates that GPIO4 is being used. Setting this bit to 0 means TDM1 is

being used. The ADM1029 can detect on power-up if TDM1 is connected. If

so then this bit is set to 0, otherwise it is set to 1. The default setting can be

overwritten by software.

GPIO 5 = ?

R/W

Indicates that GPIO5 is being used. Setting this bit to 0 means TDM2 is

being used. The ADM1029 can detect on power-up if TDM2 is connected. If

so then this bit is set to 0, otherwise it is set to 1. The default setting can be

overwritten by software.

GPIO 6 = ?

R/W

Indicates that GPIO6 is being used. Setting this bit to 0 means TDM2 is

being used. The ADM1029 can detect on power-up if TDM2 is connected. If

so then it is set to 1. The default setting can be overwritten by software.

Reserved

Unused. Will read back 0.

NOTE

Question marks on this and following pages indicate bit settings that depend on the state of certain pins on power-up.
