IBM Processor for Network Resources
14.5: LINKC Configuration 3 Transmit & Receive Control Register
This register contains the information which controls the operation of configuration 3 on the transmit and
receive. See Note on Set/Clear Type Registers on page 93 for more details on addressing.

Bits 31, 30, and 29 indicate to which PHY the IBM3206K0424’s Transmit Config 3 will
be interfacing. If the configuration’s port address is all ones then the configuration is
unused and the value of the above bits doesn’t matter.

Even parity is selected when this bit is cleared. The default value is for Odd parity. Par-
ity will always be generated when the IBM3206K0424 is transmitting data. If the PHY
doesn’t check parity then don’t connect the lines.
This bit, when set to ’0’, selects a 16-bit wide data path to the PHY device. When set to
’1’, the data path width to the PHY will be eight bits. This bit has no affect on the inter-
nal SONET/SDH framer except if the internal framer has been selected as the Rx PHY
device but not as the Tx PHY device. In this case, a ’1’ on this bit will allow FYT-
DAT(15-13) to be used for the 16-bit external Tx PHY device, while a zero will allow
FYTDAT(15-13) to be used for the Rx HDLC controller. This implies that it is not possi-
ble to use the internal RX framer, the RX HDLC interface, and an external 16-bit TX
framer at the same time.
