This register is used to set the operating mode of the ADNS-4000.
Read operation to REST_MODE_CONFIG indicates which mode the sensor is in. Write operation
into this register will force the sensor into rest modes (Rest 1, 2 or 3). Write the value 0x40 into
0x45 register to force sensor into Rest 1, 0x80 to Rest 2 or 0xC0 to Rest 3. To get out of any
forced rest mode, write 0x00 into this register to set back to normal mode.
Note: Write 0x00 to register 0x22 during start up sensor initialization to enable confi guration
to this register.
Address: 0x63

Various.
This register is used to enable burst mode. Burst is initiated by a read of this register, which
will then return continuous data starting from the address stored in BURST_READ FIRST
register through register 0x09. If burst operation is not terminated at this point, the internal
address counter stops incrementing and register 0x09 value will be returned repeatedly. Burst
operation is terminated when NCS is asserted high. For more information, refer to Burst Mode
Operation.
