Byte Vector (6)
| Entry | |
|---|---|
| R0 | Reason code |
| R1 | First argument |
| R2 | Second argument |
Use
This vector is called to indirect all calls to OS_Byte.
Notes
OS_Byte is entered with interrupts disabled, so claimants of this vector should focus on rapid execution, else your routine must enable interrupts and be prepared to be re-entered.
The default action is to call the MOS byte handler.
