The default register value is 00h. If the register value is 00h, the I2C slave address is

60h and a value of 60h is transmitted in response to a read command. If the register is

written to a value other than 00h, the I2C slave address is the lower seven bits of the

actual register value and the actual register value is transmitted in response to a read

command.

7.7.12 DSP Configuration Registers (DSP_CFG_Ux)

The DSP Configuration registers (DSP_CFG_Ux) are a series of registers that affect the

DSP data path.

There are 5 DSP Configuration registers, however, only DSP_CFG_U1, DSP_CFG_U4

and DSP_CFG_U5 are used when the device is in SPI or I2C mode. The DSP_CFG_U2

and DSP_CFG_U3 registers are for factory use only and are used for internal tests.

7.7.12.1 DSP_CFG_U1 - DSP user configuration #1 register (address 40h)

The DSP user configuration register #1 is a user programmable read/write register that

contains DSP specific configuration information. This register is included in the read/write

array error detection.

Changes to this register reset the DSP data path. The contents of the SNSDATA_x

registers are not guaranteed until the DSP has completed initialization as specified in

Table 101. Reads of the SNSDATA_x registers and sensor data requests should be

prevented during this time.
