12.3.16 Too-Long Frame Receive Counter Register (TLFRCR)
TLFRCR is a 32-bit counter that indicates the number of frames received with a length exceeding
the value specified by the receive frame length register (RFLR). When the value in this register
reaches H'FFFFFFFF, the count is halted. TLFRCR is not incremented when a frame containing
residual bits is received. In this case, the reception of the frame is indicated in the residual-bit
frame counter register (RFCR). The counter value is cleared to 0 by a write to this register with
any value.
