Table 64 Suggested Sequence of Register Writes for WM8352 Configuration in Development Mode
Note that configuration only includes registers that are required for starting up correctly. All other
register settings should be loaded after the WM8352 has started up.
Most of these control fields are described here within Section 14. See Section 11.6 for details of
Register Locking. See Section 20 for details of the GPIO configuration fields. See Section 17.7 for
details of the Battery Charger configuration.
When using the /RST signal to trigger configuration, writing to the _ENSLOT and RSTB_TO fields
can be omitted (the reset and power-up sequence has already taken place, so the write would have
no effect). However, additional writes to R13 or R176 should be added to enable the DC-DC
converters and LDO regulators one by one.
