When A13 is high, the data or connection memory can be accessed by the microprocessor port. Bit 1 - 0 in the
Control Register determine the access to the data or connection memory (CM_L or CM_H).
Notes:
1. A13 must be high for access to data and connection memory positions. A13 must be low to access internal registers.
2. Channels 0 to 31 are used when serial stream is at 2.048 Mbps.
3. Channels 0 to 63 are used when serial stream is at 4.096 Mbps.
4. Channels 0 to 127 are used when serial stream is at 8.192 Mbps.
5. Channels 0 to 255 are used when serial stream is at 16.384 Mbps.
