SPI2 register description

11.1

SPI2_WHO_AM_I (0Fh)

WHO_AM_I register (r). This is a read-only register. Its value is fixed at 6Ch.

11.2

SPI2_STATUS_REG_OIS (1Eh)

The SPI2_STATUS_REG_OIS register is read by the Auxiliary SPI (r).

11.3

SPI2_OUT_TEMP_L (20h) and SPI2_OUT_TEMP_H (21h)

Temperature data output register (r). L and H registers together express a 16-bit word in

two’s complement.
