There appears to be an error in UG-570 Rev A Page 24 last paragraph which states the following:
"This mode is enabled by setting Bit D1, Fast Lock Profile Pin Select in Rx Register 0x25A and/or Tx Register 0x29A along with enabling fast lock mode in the same registers. When this is set, CTRL_IN0 through CTRL_IN2 select the profile (if both pin select bits are set, profiles are selected in parallel)."
The actual pin control lines are CTRL_IN1 through CTRL_IN3. Please confirm this information is correct.
