The SPI and hardware modes are not supported.
RSER has been renamed to RSERI.
RCLK has been renamed to RCLKI.
TSER has been renamed to TSERO.
TCLK has been renamed to TCLKE.
The Facilities Data Link (FDL) support is available through software only. The TLINK, RLINK, TLCLK,
RLCLK pins are not available on the DS33R11.
Multiplexed Microprocessor Bus mode is not supported on the DS33R11.
The Extended System Information Bus (ESIB) is not supported on the DS33R11.
The MODEC pins serve the function of the DS2155’s BTS pin.
The interim LIU/Framer clock signals RCLKI, RCLKO have been renamed to RDCLKI, RDCLKO to avoid
confusion with the receive clock connections between the transceiver and the Ethernet mapper.
The interim LIU/Framer clock signals TCLKI, TCLKO have been renamed to TDCLKI, TDCLKO to avoid
confusion with the receive clock connections between the transceiver and the Ethernet mapper.
RSER has been renamed RSERO.
RCLK has been renamed RCLKO.
TSER has been renamed TSERI.
TCLK has been renamed TCLKT.
