14.2
The data memory field is a read only address range used to monitor the data being received by the input streams.
Addressing into each of the streams is illustrated in Table 17.
Within each stream group, the mapping of each of the actual input streams, STiAn and STiBn, depends on the input
rate programmed into the Group Control Registers. The address offsets to these data areas for each of the input
streams are illustrated in Table 18.
