12.3.15 Too-Short Frame Receive Counter Register (TSFRCR)
TSFRCR is a 32-bit counter that indicates the number of frames of fewer than 64 bytes that have
been received. When the value in this register reaches H'FFFFFFFF, the count is halted. The
counter value is cleared to 0 by a write to this register with any value.
