When A11 is high, the data or the connection memory can be accessed by the microprocessor port. The Bit 0 to Bit
2 in the control register determine the access to the data or connection memory
Notes:
1. MSB of address must be high for access to data and connection memory positions. MSB must be low for access to registers.
2. Channels 0 to 31 are used when serial stream is at 2.048 Mb/s.
3. Channels 0 to 63 are used when serial stream is at 4.096 Mb/s.
