SBUF holds only 0x00, which is then fed through the rest of my code and messes it all up.
Why is this occuring? I don't know why it's occuring, but I think your application should be designed so as to be tolerant of it happening! It is quite common to get a few junk characters on any serial interface at startup - so your code should be sufficiently resilient to not be "messed up" by it. |

| Yes they are set - Why? | 01/01/70 00:00 | |

Thanks - Done | 01/01/70 00:00 | |
| aren't the LPC9xx's pins... | 01/01/70 00:00 | |
| Yes but - it also happens in the real hardware | 01/01/70 00:00 | |
| the point of asking nonsense questions... | 01/01/70 00:00 | |
| Understood, appreciate being 2nd guessed | 01/01/70 00:00 | |
