AC CHARACTERISTICS (DIGITAL)
VDDD =VDDA =VDDO 4.5 to 5.5 V; all voltages referenced to ground (pins 2, 9 and 23); Tamb = 40 to +85 °C; unless
otherwise specified.
Notes
1. A clock frequency of up to 96fs is possible in the event of a rising edge of BCK occurring during SYSCLK = LOW.
2. A clock frequency of up to 64fs is possible in the event of a rising edge of BCK occurring during SYSCLK = LOW.
