Like stated before, there is a delay of three times the frame length (default: 30 ms)
between the transfer of a new control block from the host to the JADE and the new
settings being reported in the status data (transferred from the JADE to the host) due to
the internal buffering pipeline of the JADE.
The structure of the control and status data blocks is identical. The host writes the control
block to change the settings of the JADE and reads the status block to evaluate the
current settings of the JADE.
The control/status block is organized in 8-bit words and has the following structure:
G723C
OPT2
EVOL
DVOL
Note: Unless otherwise indicated, the host has to switch the MODE to neutral for at least
Semiconductor Group
3 frames (default: 30 ms) before it can change the control block. Only the
underlined bits may also be changed on the fly disregarding that rule. After Reset,
the JADE is automatically in the neutral mode, so changes to the control block can
be done immediately after the JADE has finished its initialization phase (see
Section 6.2.3).
