Depending on the usage, set the control signal as shown below:
- When an oscillator circuit (20MHz) is
used
- When a 20 MHz clock of 3.3V level is
input from the OSCIN pin
(PLL is used)
- When an oscillator circuit (40MHz) is
used
- When a 40 MHz clock of 3.3V level is
input from the OSCIN pin
(PLL is not used)
