## Detailed Description

MOST\_REG.

This event transports a register read or write result (e.g. reading the routing engine of the OS8104). Unlike the special register event (**MostGenReg**) this event does not occur spontaneous.

- •

  ReadRequest = 2: request of a register read operation

- •

  WriteRequest = 3: request of a register write operation

- •

  ReadResult = 4: result of a register read operation

- •

  WriteResult = 5: result of a register write operation

- •

  ReadFailed = 6: register read operation failed

- •

  WriteFailed = 7: register write operation failed
