7.6.1 Register List

Fields indicated with Reserved must be written only with indicated value, otherwise improper device operation may occur. The R/W column indicates the Read-Write status of the corresponding field. A ‘R/W’ entry indicates read and write capability, a ‘R’ indicates read-only, and a ‘W’ indicates write-only.

For registers with R and R/W fields, write the reset value to the field when setting the R/W fields.
