TS-8950-4900 DIO Table
From embeddedTS Manuals
The GPIO numbers in the table below are relevant to how the Linux references these numbers. The CPU documentation refers to bank and IO while Linux flattens this out to one number space.

- ↑ The pad name does not often correspond with the functionality of the IO we use, but can be used to reference the pad in the CPU manual.
- ↑ This can be used to detect power failing from the optional supercaps providing about 10 seconds of safe shutdown (depending on power consumption from build options)
- ↑ This is not normally controlled manually, but will be pulsed in u-boot on startup.
- ↑ Used for onboard flash CS
- ↑ 5.0 5.1 Used for communication with RTC and FPGA
