14.0
This section describes all the memories and registers that are used in this device.
14.1
Address range 000000 - 017FFF hex.
On power-up, all Connection Memory locations are initialized automatically to 00000000 hex, using the Block
Initialization feature, as described in Section 14.7 and Section 14.8.
The 32 bit Connection Memory has 24,576 locations. Each 32 bit long-word is used to program the desired source
data and any other per-channel characteristics of one output time-slot.
The memory map for the Connection Memory is sub-divided into 24 blocks, each corresponding to one of the
possible 24 output stream group numbers. The address ranges for these blocks are illustrated in Table 13.
