H_RESOLUTION
Access: Read/Write
Data Type
USAGE : This register is used to set the resolution configuration of sensor up to 2000cpi. For resolution setting at
1600cpi and below, configuration via Configuration_Bits register, 0x12 is still effective when H_RES_EN bit is set to
zero.
POWER_UP_RESET
Access: Write
Data Type: 8 Bit integer
USAGE: Write 0x5a to this register to reset the chip. All settings will revert to default values. Reset is required after
recovering from shutdown mode.

SHUTDOWN
Access: Write Only
Data Type: 8 Bit integer
USAGE: Write 0xe7 to set the chip to shutdown mode, use POWER_UP_RESET register (address 0x3a) to power up the
chip.

Description
0 = Resolution setting will follow the value as per configuration in Configuration_Bits register, 0x12
1 = Enabled high resolution up to 2000cpi. Resolution setting will follow the configuration
as per H_RES2-0 bits in this register and setting in register 0x12 will be ignored.
