The TXIDL4 register contains the fourth byte of the Transmit Idle Cell Header. (See
0x14—TXIDL1.)
The RXHDR1 register contains the first byte of the Receive Cell Header. The header
values direct ATM cells to the UTOPIA port if an incoming ATM cell header matches
the value in the header register. Receive Header Mask Registers further qualify ATM
cell reception. This header consists of 32 bits divided among four registers.
