GPIO REGISTERS
Table 49. REGISTER 04H GPIOS SUPPORTED BY CONTROLLER (POWER-ON DEFAULT 7FH)
Bit
Name
R/W
Description
0
GPIO 0 = 1 (Pin 19)
R
This bit set to 1 means the ADM1029 can support GPIO0, available on Pin 19.
1
GPIO 1 = 1 (Pin 20)
R
This bit set to 1 means the ADM1029 can support GPIO1, available on Pin 20.
2
GPIO 2 = 1 (Pin 11)
R
This bit set to 1 means the ADM1029 can support GPIO2, available on Pin 11.
3
GPIO 3 = 1 (Pin 13)
R
This bit set to 1 means the ADM1029 can support GPIO3, available on Pin 13.
4
GPIO 4 = 1 (Pin 14)
R
This bit set to 1 means the ADM1029 can support GPIO4, available on Pin 14.
5
GPIO 5 = 1 (Pin 16)
R
This bit set to 1 means the ADM1029 can support GPIO5, available on Pin 16.
6
GPIO 6 = 1 (Pin 17)
R
This bit set to 1 means the ADM1029 can support GPIO6, available on Pin 17.

Table 50. REGISTER 05H GPIO PRESENT/AIN (POWER-ON DEFAULT 0????111)
Bit
Name
R/W
Description
0
GPIO 0 = 1
R/W
Indicates that GPIO0 is being used. Set to 1 on power-up, but can be
overwritten by software. Setting this bit to 0 means AIN0 is being used.
1
GPIO 1 = 1
R/W
Indicates that GPIO1 is being used. Set to 1 on power-up, but can be
overwritten by software. Setting this bit to 0 means AIN1 is being used.
2
GPIO 2 = 1
R/W
Indicates that GPIO2 is being used. Set to 1 on power-up, but can be
overwritten by software.
3
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.
4
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.
5
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.
6
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.
7
Reserved
R
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.
