1. For byte register accesses, the address range of ba3, ba2, ba1, ba0 is hexadecimal 0 – F. The bits d7 through d0 are data that is written
2. For nibble register accesses, the address range of na3, na2, na1, na0 is hexadecimal 0 – 5. The bits d3 through d0 are data that is written
3. The bits a1 through a3, dm, and i1 through i8 are data that is written to the eoc register.
4. For non–ISDN applications, the data written to the eoc register uses the convention that bit a1 is the most significant bit and bit i8 is the
5. The receiving device does not issue a response to a register write command.
6. Byte or nibble read commands consist of byte 1 only. Byte 2 is not transmitted to the MC145572. In response to a read command, the
