When this bit is 0, GPIO12 is configured as an input; otherwise, it is an output.
When this bit is 0, GPIO12 is active low; otherwise, it is active high.
When this bit is 0, GPIO13 is configured as an input; otherwise, it is an output.
When this bit is 0, GPIO13 is active low; otherwise, it is active high.
When this bit is 0, GPIO14 is configured as an input; otherwise, it is an output.
When this bit is 0, GPIO14 is active low; otherwise, it is active high.
When this bit is 0, GPIO15 is configured as an input; otherwise, it is an output.
When this bit is 0, GPIO15 is active low; otherwise, it is active high.
For factory use only. Do not write to this register.
This register contains the THERM limit for the internal temperature channel.
Exceeding this limit causes the THERM output pin to be asserted.
This register contains the THERM limit for the TDM1 temperature channel.
Exceeding this limit causes the THERM output pin to be asserted.
This register contains the THERM limit for the TDM2 temperature channel.
Exceeding this limit causes the THERM output pin to be asserted.
This register contains the T
