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 (PORB). Failure to correctly set these bits
may result in the device operating in an unexpected way.
Some registers do not appear in this list, for example 07 and 08. 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.
