TSFRCR is a 16-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'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—Too-Short Frame Receive Count 15 to 0 (TSFC15 to TSFC0): These bits indicate
the count of frames received with a length of less than 64 bytes.
