TS-73X0 Errata xuartgpio
|Synopsis||PC/104 XUART pins cannot be used as GPIO|
|Affected||TS-7350/70 All FPGA Revs|
|Status||No workarounds available|
The two XUARTs on PC/104 pins A12, A15, A18, and A19 are unavailable as GPIO pins and are always XUART pins if the PC/104 bus is in GPIO mode, `pc104off`. If the PC/104 bus is in PC/104 mode, `pc104on`, then these pins will be used in their PC/104 modes and not available as XUART. This is not considered a bug at this point in time.
