I2C and SMBus are designed in such a way that an SMBus read transaction can be seen as a write transaction by certain chips. This protection is enabled by default when certain prerequisite settings are enabled. Options Please refer to section 6.5.2 of the datasheet for more information on how to read multiple bytes.

To do a block read, you use the same read command that you do to read a single byte, but you set the number of bytes to read to however many bytes you want to read. The returned word 0x9489 should be interpreted as 0x89 0x94 which is the indeed the (WM8994) device ID.
