“;” – semi-colon.

Example: TTS,text to speech; After this is added using the ABBR_ADD command, when the text

“TTS” is sent as part of the convert data, the WTS701 will speak “text to speech” instead of T T S.

Note: when deleting an abbreviation, the abbreviation text is optional.

To delete the TTS example, only “TTS,;” is necessary.

7.8.2 Abbreviation Table Format

The format of the abbreviation table returned with the ABBR_RD command is:

Abbreviation entry - Marker + Count + XXX + 0x00 + YYYY + 0x00.

Marker – The marker will be either 0xfe for active abbreviation or 0xfc for a deleted abbreviation.

Count – The byte count for this entry including the Marker, Count, XXX, YYYY, and zeros.

XXX – the abbreviation characters.

0x00 – Null terminator.

YYYY – abbreviation text.

0x00 – Null terminator.

The unused data are always 0xff.

7.8.3 Command Execution

ABBR_NUM & ABBR_MEM -

These commands are executed by sending the command and

command data, waiting for R/ B to be ready, then receiving two bytes from MISO. The first byte

received is the MSB, and the second is LSB.

ABBR_RD – This command is executed by sending the command and command data, waiting for

R/ B to be ready, then receiving 2048 characters (the entire abbreviation table).

ABBR_ADD & ABBR_DEL – These commands are executed by sending the command and command

data, followed by the abbreviation data formatted as described in subsection 7.8.1. When the WTS701

is ready for the next step, it will generate an IABB interrupt. After the interrupt, send the

ENTER_RSSM (0x0c + 0x00) command. After issuing the command wait for 100ms. After the timeout,

the WTS701 will have programmed the new abbreviation entry and be ready to accept more

commands. Adding or removing an abbreviation will reset the configuration registers to their default

values.
