Summary of Memory Operations
Application
Writing a PCM idle value to
the upstream DM data field
The MACR value specifies
the bandwidth and bit
position at the PCM
interface
Writing to a single tristate
field location
Writing to all tristate field
locations
Reading a single tristate
field location
Writing to the CM data field 8 bit value
Semiconductor Group
MADR
8 bit, 4 bit or 2 bit idle
value to be transmitted
at the PCM interface
8 bit value transmitted
at the upstream or 8 bit
value received at the
downstream PCM
interface
