RFCR is a 16-bit counter that indicates the number of frames received containing residual bits
(less than an 8-bit unit). When the value in this register reaches H'FFFF (65,535), the count is
halted. The counter value is cleared to 0 by a write to this register (the write value is immaterial).
Bits 31 to 16—Reserved: These bits are always read as 0. The write value should always be 0.
Bits 15 to 0—Residual-Bit Frame Count 15 to 0 (RFC15 to RFC0): These bits indicate the count
of frames received containing residual bits.
