Microprocessor interface supports 8 bit wide or 16-
bit wide read/write accesses.
Supports polled or interrupt-driven environments.
Supports burst mode “Read and Write” operations
between the “l(fā)ocal” microprocessor and the UNI on-
chip registers and RAM locations.
Includes a “Loss of Clock Signal” protection feature
that terminates “Read/Write” cycles with the local
μ
P during a “Loss of Clock signal” event.

Supports Line, PLCP and Cell Loop-back Modes
Supports Line-Side Testing
Contains an on-chip Test Cell Generator and an on-
chip Test Cell Receiver
Test Cell Generator can generate a “continuous”
stream of test cells, or a “one-shot” burst of 1024
test cells.
The Test Cell Receiver identifies, collects and eval-
uates Test Cells for errors.
The Test Cell Receiver also reports the occurrence
of errors to the user.

ECTION
Consists of an on-chip “Read/Write” register that
allows the user to control the state of 6 output pins.
Consists of an on-chip “Read-Only” register that al-
lows the user to monitor the state of 3 input pins.
