| PsiFS_CheckUID (SWI &520CE) | |||
| Calculate the checksum for a UID | |||
| On entry: | R0 = | UID1 | |
| R1 = | UID2 | ||
| R2 = | UID3 | ||
| On exit: | R0 = | calculated checksum, UID4 | |
| Interrupts: | Interrupt status is undefined Fast interrupts are enabled | ||
| Processor mode: | Processor is in SVC mode | ||
| Re-entrancy: | SWI is not re-entrant | ||
| Use: | Calculate the checksum for an EPOC UID. The resulting value should be used for UID4. | ||
