PKT_VERSTRING Resp

onse field (n + 2 bytes) this field is a null-terminated string that contains the product version number

for example

“V100.E100.XXXX.C106.G514.R007.A0030608.C0020208”

Where the value after the “R” indicates the software release. For more detailed information on software modifications see

PKT_READY field (1 byte total) a packet containing this field is output by the AMBE-3000™ Vocoder Chip after a hard

reset (TQFP pin 113 / BGA pin D6) or packet reset (using a PKT_RESET or PKT_RESETSFTCFG field) when it is ready to

receive packets.

PKT_HALT field (1 byte total) this field will cause the AMBE-3000™ Vocoder Chip to enter halt mode. In this mode the

AMBE-3000™ Vocoder Chip will consume the least amount of power possible. The only way to exit this mode is to perform

a hardware reset.

The PKT_HALT field does not return a Response field.

PKT_RESET field (1 byte total) this field will cause the AMBE-3000™ Vocoder Chip to be reset. As a result, the AMBE-

3000™ Vocoder Chip will lose all prior configuration settings and reset itself to the default power up state. Note that the

AMBE-3000™ Vocoder Chip will re-read the configuration pins.
