Busy Box Status and Contol Registers | ||||
| Address | Read/Write | Name | Description | Default Value |
|---|---|---|---|---|
| 0x0001 | RW | TX module | For sending messages to DRORCs. Bit 7-0 is TX data. Bit 15-8 gives channelnumber in hexadecimal. Any value greater than the actual number of channels will result in a broadcast on all channels. | TBD |
| 0x1XXX | RW | RX memory | Memory where all messages received from DRORCs will be stored. | TBD |
| 0x2000 | R | RX memory pointer | Holds the value where the next message will be written in RX memory. | TBD |
| 0x2001 | R | EventID count | Number of eventIDs stored in the FIFO, excluding the eventID currently being matched, if any. | TBD |
| 0x2002 | R | Current EventID(35-32) | The EventID which is currently being matched. | TBD |
| 0x2003 | R | Current EventID(31-16) | TBD | |
| 0x2004 | R | Current EventID(15- 0) | TBD | |
| 0x2005 | R | Newest EventID(35-32) | The EventID most recently received from the TTC system. | TBD |
| 0x2006 | R | Newest EventID(31-16) | TBD | |
| 0x2007 | R | Newest EventID(15- 0) | TBD | |
| 0x2008 | RW | L0 trigger timeout | Number of clock cycles 'busy' will be asserted after an L0 trigger. Note: The busy will not be deasserted if the buffers are full. | TBD |
| 0x2009 | RW | FEE buffers available | Config: Holds the number buffers assumed on the FEE. | TBD |
| 0x200A | RW | Halt FW matching | If LSB is set to 1 the internal FSM will halt in a wait state. | TBD |
| 0x200B | w | Force match | Writing 0x1 when FSM halt is set, will force the FSM to move on to the next EventID even if it is not matched. | TBD |
| 0x200C | RW | Re-Request Timeout | Number of clock cycles to wait in between sending requests to the DRORCs. | TBD |
| 0x200D | R | Current RequestID | Holds the RequestID the BusyBox is using to request eventIDs from the DRORCs. | TBD |
| 0x200E | R | Retry Count | Number of times requests have been sent to DRORCs. | TBD |
| 0x2010 | R | Busy time(31-16) | Holds value of counter for number of clock | TBD |
| 0x2011 | R | Busy time(15- 0) | cycles BUSY has been asserted. | TBD |
| 0x2012 | RW | RX mem filter | Allows filtering of messages that are stored in RX memory. Bit 7-0 is the pattern that will be matched with the channelnumber of the message. Bit 15-8 allows enableing matching of individual bits 7-0. | TBD |
| 0x21XX | RW | Channel Registers | 'XX' in the address gives the channelnumber in hexadecimal. Bit 0 is enable/disable (0/1) Bit 1 indicates that the current EventID has been matched on this channel. | TBD |
