The clock should be running during the reset time. When
no clock can be guaranteed in microcontroller mode, a soft
reset should be given when the system is running by
writing to register 7FH.

In this chapter the application modes for static mode and
microcontroller mode are described.
The UDA1355H can be controlled by static pins, the
L3-bus or I
by the pin count, only basic functions are available in static
mode. For optimum use of the UDA1355H features, the
microcontroller mode is strongly recommended.
There are 11 application modes available in the static
mode and 14 application modes in microcontroller mode.
The application modes are explained in the two sections:
Section 8.2 explains the application modes 0 to 10.
Section 8.4 explains the more advanced features of
modes 0 to 10 and modes 12 to 14 available in the
microcontroller mode.
8.1
The default values for all non-pin controlled settings are
identical to the start-up defaults from the microcontroller
mode. Whether BCK and WS are master or slave depends
on the selected application mode.
Table 9 defines the pin functions in static mode.
