ATM Physical Interface (PHY) Devices
0x22—TXIDL3 (Transmit Idle Cell Header Control Register 3)
The TXIDL3 register contains the third byte of the Transmit Idle Cell Header. It contains the header value that is
inserted in idle cells transmitted from the device. This header consists of 32 bits divided among four registers.
Cell generation is described in detail in
0x23—TXIDL4 (Transmit Idle Cell Header Control Register 4)
The TXIDL4 register contains the fourth byte of the Transmit Idle Cell Header. It contains the header value that
is inserted in idle cells transmitted from the device. This header consists of 32 bits divided among four registers.
Cell generation is described in detail in
