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 P
and the MTSXL.
