33 / 52 page  20 Software (Continued) CVOC Check Vocabulary Checks (checksum) if the IVS data was correctly pro- grammed to the ROM or flash device If the vocabulary data is correct the return value is 1 Other- wise the return value is 0 If the current vocabulary is undefined ERR INVALID is re- ported Example CVOC Byte sequence Microcontroller 2B AA CompactSPEECH 2B 01 Description Check the current vocabulary The CompactSPEECH responds that the vocabulary is OK DM Delete Message Deletes the current message Deleting a message clears its message tag Deleting the current message does not cause a different message to become current The current message is unde- fined If for example you issue the GTM command to skip to the next message the first message that is newer than the just deleted message is selected as the current mes- sage The memory space released by the deleted message is im- mediately available for recording new messages Example DM Byte sequence Microcontroller 0A CompactSPEECH 0A Description Delete current message DMS Delete Messages tag ref tag mask Deletes all messages whose message tags match the tag ref parameter Only bits set in tag mask are compared ie a match is considered successful if message tag and tag task e tag ref and tag mask where and is a bitwise AND operation After the command completes execution the current mes- sage is undefined Use the GTM command to select a mes- sage to be the current message The memory space released by the deleted message is im- mediately available for recording new messages Example DMS FFC2 003F Byte sequence Microcontroller 0B FF C2 00 3F CompactSPEECH 0B FF C2 00 3F Description Delete all old incoming messages from mailbox Number 2 in a system where the message tag is encoded as follows Bits 0 – 2 mailbox ID 8 mailboxes indexed 0 to 7 Bit 3 newold message indicator 0 Message is old 1 Message is new Bits 4 – 5 message type 00 ICMmemo 01 OGM 10 Call transfer message Bits 6 – 15 not used Note The description of the tag is an example only All bits of the tag are user-definable GCFG Get Configuration Value Returns a sequence of two bytes with the following informa- tion Bits 0 – 7 Magic number which specifies the Compact- SPEECH firmware version Bits 8 – 9 Memory type 00 Reserved 01 Reserved 10 Serial Flash 11 Reserved The command should be used together with the CFG and INIT commands during CompactSPEECH initialization See the CFG command for more details and an example of a typical initialization sequence Example GCFG Byte sequence Microcontroller 02 AA AA CompactSPEECH 02 02 01 Description Get the CompactSPEECH magic number The CompactSPEECH responds that it is Version 1 with Serial Flash http www nationalcom 33 |
