Table 75 PKT_RESETSOFTCFG Field
The PKT_RESETSOFTCFG field does not return a Response field; however, the AMBE-3000™ Vocoder Chip does output a
PKT_READY packet after every reset (including both hard resets and packet resets). The PKT_READY packet can therefore
be viewed as a response packet to the packet containing a PKT_RESETSOFTCFG field.
PKT_GETCFG field (1 byte) this field will cause the AMBE-3000™ Vocoder Chip to output a response field which contains
the 3 bytes which were read from the configuration pins after reset. Note that this does not cause the configuration pins to be
re-read, it merely reports back what the state of the pins were upon power-up or reset.

PKT_READCFG field (1 byte total) this field will cause the AMBE-3000™ Vocoder Chip to output a response field which
contains the 3 bytes which are read from the configuration pins after the PKT_READCFG field is received. Note that if the
signal levels on the configuration pins have changed since their reset levels, then CFG0-CFG2 reported by the response packet
will reflect that change. Note that although this packet causes the configuration pins to be re-read and sent back in a response
packet, the AMBE-3000™ Vocoder Chip does not change its configuration as a result of receiving this packet.
