VP310

PRELIMINARY DATA

16

Selecting the correct bit of register (25) VIT_MODE, if known, programs the convolutional code

rate. If the code rate is unknown, some or all of the bits of VIT_MODE may be set to force the

VP310 to search for the code rate.

Finally, the VP310 is given a GO command, register (27) GO = 1, to release the state machine

and to start the signal acquisition sequence. This is summarised as an example in the following

flow diagram.
