PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE

buffer as a word wide stream (along with a bit marking the first word of the cell)

at instantaneous rates of up to 52 MHz.

The cell data structure supported is described in the Operation section.

9.18.2 Transmit Interface

The drop side transmit interface can be accessed through a generic 19-bit wide

interface. External circuitry is notified using the TCA signal when a cell may be

written to the transmit FIFO. The cell is written to the FIFO as a word wide

stream (along with a bit marking the first word of the cell) at instantaneous rates

of up to 52 MHz.

The cell data structure supported is described in the Operation section.

9.19

Parallel I/O Port

The Parallel Input/Output Port block provides four generic outputs and four

generic inputs that can be used to control and monitor front end PMD devices.

9.20

JTAG Test Access Port

The JTAG Test Access Port block provides JTAG support for boundary scan. The

standard JTAG EXTEST, SAMPLE, BYPASS, IDCODE and STCTEST

instructions are supported. The S/UNI-PLUS identification code is 053470CD

hexadecimal.

9.21

Microprocessor Interface

The microprocessor interface block provides normal and test mode registers, and

the logic required to connect to the microprocessor interface. The normal mode

registers are required for normal operation, and test mode registers are used to

enhance the testability of the S/UNI-PLUS.
