System Procedures for Initialization, Changing Data Rates, and Switching Between Master and Slave Mode
36
SLES089—January 2004
TAS5066
Figure 45 shows the procedure to change the data rate using the DBSPD terminal and then restore the
register settings. In this example, the ERR_RCVRY terminal is used to hold off system re-initialization after
RESET is released. This permits the system controller to have as much additional time as necessary to restore
the register settings.
Once the data rate is set, the ERR_RCVRY and MUTE terminal signals are set high and the system
re-initializes.

Figure 45. Changing the Data Sample Rate With an Unstable MCLK_IN Using the DBSPD Terminal
Because this sequence employs the RESET terminal, the internal register settings are set to the default
values.
Figure 45 shows the procedure to change the data rate using Register X02 D7 and D6 and then restore the
other register settings. In this example, the ERR_RCVRY terminal is used to hold off system re-initialization
after RESET is released. This permits the system controller to have as much additional time as necessary to
restore the register settings.
Once the data rate is set, the ERR_RCVRY and MUTE terminal signals are set high and the system
re-initializes.
