VME Cycle Error Register
VME Write Transfer Byte Count Register
VME Cycle Error Codes:
- 0x100 Timeout
- 0x110 USB Protocol Error: invalid parameter
- 0x111 USB Protocol Error: USB write error
- 0x112 USB Protocol Error: USB read error
- 0x113 USB Protocol Error: USB read length error
- 0x211 VME Bus Error
- 0x212 VME_RETRY_ERROR
- 0x214 VME Arbitration Timeout
Note: The 0x100 timeout error occurs if the VME master logic is "dead" for one second. This
situation can occur if the VME slave generates DTACK_L in a fashion that violates the VME
specification. The timeout error does not occur with properly working VME slave hardware.
