Synopsis
Port Number: 83h
Function: USB Write-Pipe Events
This port reports when a USB transaction on a "write" pipe has finished. This port hypothetically holds the values for ports A8h-AFh.
| This port only exists on the the TI-84 Plus and the TI-84 Plus Silver Edition. On the standard TI-83 Plus, it acts as a shadow of port 03. On the TI-83 Plus Silver Edition, this port has no effect. |
Read Values
Reading from this port also clears it. Remember the value you read, because you can't go back and read it again.
- Bit 0: Hypothetically, set if a write transaction has finished on pipe 8.
- Bit 1: Hypothetically, set if a write transaction has finished on pipe 9.
- Bit 2: Hypothetically, set if a write transaction has finished on pipe A.
- Bit 3: Hypothetically, set if a write transaction has finished on pipe B.
- Bit 4: Hypothetically, set if a write transaction has finished on pipe C.
- Bit 5: Hypothetically, set if a write transaction has finished on pipe D.
- Bit 6: Hypothetically, set if a write transaction has finished on pipe E.
- Bit 7: Hypothetically, set if a write transaction has finished on pipe F.
Write Values
- No effect
Comments
See port 82. I'm not sure anything on this page has actually been tested, but it should be true.
