ERROR FLAGS REGISTER

Address: 0x03, Reset: 0x00, Name: ERR_FLAGS

The error flags register allows the user to determine if an error has occurred. To clear the error flags register, write the special 16-bit SPI

command 0x6CA9 to the device. This SPI command does not trigger the invalid R/W address error. When CRC is enabled, the user must

include the correct CRC byte during the SPI write for the clear error flags register command to succeed.

RW_ERR_FLAG

Error flag for invalid read/write address. The error flag asserts during a SPI

the target address of a SPI write is does not exist or is read only.

BURST ENABLE REGISTER

Address: 0x05, Reset: 0x00, Name: BURST_EN

The burst enable register allows the user to enable or disable burst mode. When enabled, the user can send multiple consecutive SPI

commands without deasserting CS.

SOFTWARE RESET REGISTER

Address: 0x0B, Reset: 0x00, Name: SOFT_RESETB

Use the software reset register to perform a software reset. Consecutively, write 0xA3 followed by 0x05 to this register, and the registers of

the device reset to their default state.
