ELECTRICAL CHARACTERISTICS (Tamb = 0 to 70°C, VCC = 5V ± 5%)
All DC characteristic are valid 250µs after VCC and clock have been applied. CL is the max. capacitive
load and RL the test pull up resistor.

Notes:
1. With Extra Bit operating mode insert this time becomes 3 tCK.
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).
