Function

Frame Measuring Inputs: These inputs are used

as frame evaluation inputs.

Address Bus Bit 0 to 4: These inputs interface to

the systems address bus to select an internal

register for a read or write access.

Chip Select: (low active) A low level selects the

MTSXL for a register access operation.

Reset: A high signal on this Input forces the MTSXL

into reset state.

Write: (low active) This signal indicates a write

operation.

Read: (low active) This signal indicates a read

operation.

Synchronization Pulse: The MTSXL is

synchronized to the PCM system via this line.

Data Bus: These pins transfer data between the µP

and the MTSXL.
