The value written to the downstream CM data field location is transmitted repeatedly in
every frame (CFI idle value) during the corresponding downstream CFI timeslot until a
new value is loaded or the ‘ P channel’ function is disabled. There are no interrupts
generated.
The upstream CM data field can be read at any time. The CM data field is updated in
every frame. The last value read represents the value received. There are no interrupts
generated.
For frame-synchronous exchange of data between the P and the CFI, the synchronous
transfer utility must be used (refer to chapter 5.7). Since this utility realizes the data
