Register Map
Shaded areas in the map are ‘don’t care’ and writing either 0 or 1 will not affect any function of
the device.
Bits labelled ‘Set to 0’ or ‘Set to 1’ must be set as stated during initialisation of the device,
either following power up, or after a power on reset (POR). Failure to correctly set these bits may
result in the device operating in an unexpected way.
Some registers do not appear in this list. These are either not used, or have test functionality. Do
not write to any undefined registers as this may cause the device to operate in a test mode. If an
undefined register has been inadvertently addressed, the device should be reset to ensure the
undefined registers are at default values.
