TS-73X0 Errata xuartgpio
From embeddedTS Manuals
| Synopsis | PC/104 XUART pins cannot be used as GPIO |
| Severity | Minor |
| Class | FPGA bug |
| Affected | TS-7350/70 All FPGA Revs |
| Status | No workarounds available |
Description:
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.
