Bits 15 to 0: Bit Count (BC[31:16]) - Upper 16 bits of 32 bits.

Bit Count (BC[31:0]) – These thirty-two bits indicate the number of bits in the incoming data stream. This count
stops incrementing when it reaches a count of FFFF FFFFh. This bit counter will not increment when an OOS
condition exists. This register is updated via the PMU signal (see section

9.4.5

)
