Changing Between Master and Slave Modes
The M_S terminal is set while the RESET terminal is active. Because this sequence employs the RESET
terminal the internal register settings are set to the default values.
Figure 47 shows the procedure to switch between master and slave modes 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.
