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
μ
P
and the MTSXL.
