+It is largely an example of SPI without CS, in SPI mode 0,1.
+
+Correct decodings with the ADE7758 decoder should show:
+
+ RSTATUS: 0x400
+ FREQ: 0x0 (frequency is from phase A, not connected on this device)
+ BVRMS: 0x10cd0c (context) or 0x10ccfa (nocontext)
+ BIRMS: 0x2ac (context) or 0x2a8 (nocontext)
