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