 ### Changelog
 
+#### 20210513_120hpf - PB6.47.0
+
+- Recharacterized and retuned with EVT Bucks
+  - **Top**: 5 samples (3 new ones + 2 from 20210323)
+  - **Bottom**: Same 3 samples as 20210323
+- Updated ReDC fallback per customer request.
+  - **Top**: 5.471 Ohms
+  - **Bottom**: 6.383 Ohms
+- Cal and Cal+Diag bin versions remain unchanged from 20210323 as these parameters have not been modified.
+
 #### 20210329_120hpf - PB6.47.0
 
 - Top speaker incorrectly had hpf as 150hz. Corrected fcutoff parameter on top speaker protect tunes.
@@ -33,6 +43,9 @@
     - **xmax**: 0.45mm
     - **tmax**: 130C
     - **hpf**: 120Hz
+- Updates to firmware from 6.45.0 to 6.47.0
+  - Implemented a timeout feature that allows a maximum delay between the start of the BCLK and the start of the LRCLK. If the timeout is exceeded, an error notification is sent to the driver and the command is ignored. This addresses a host-side timing issue for these signals that could lead to a no-audio situation.
+  - Fixed an issue where repeated pause/resume commands could cause pops on the output.
