Notes:

2. With Extra Bit operating mode insert these times are 80ns longer.

3. With OPCODE (C/D = I), this time becomes 4tck (6tck if E = 1). E: extra bit indication in ”operating mode” instruction.

4. For tone generation instruction, this time becomes 4tck (6tck if E = 1) E: extra bit indication in ”operating mode” instruction.

5. With extra bit operating mode insert, this time becomes 6tck.

6. The initialization routine takes 2 frames time starting from the rising edge of RESET - Any access to the device should take place after the

initialization routine is completed. (2 frames time).
