• Min / Max characteristics and specifications are guaranteed over all
• Typical characteristics and specifications are measured at nominal supply voltages and TA = 25 °C.
• VA+ = VD+ = 5V ±5%; AGND = DGND = 0 V. All voltages with respect to 0 V.
• DCLK = 4.096 MHz.
11. If a crystal is used, XIN frequency must remain between 2.5 MHz - 5.0 MHz. If an external oscillator is
12. If external MCLK is used, the duty cycle must be between 45% and 55% to maintain this specification.
13. The frequency of CPUCLK is equal to MCLK.
14. The minimum FSCR is limited by the maximum allowed gain register value. The maximum FSCR is
15. Configuration register (Config) bits PC[6:0] are set to “0000000”.
16. The MODE pin is pulled low by an internal resistor.
used, XIN frequency range is 2.5 MHz - 20 MHz, but K must be set so that MCLK is between
2.5 MHz - 5.0 MHz.
