Notes: 1. External clock is supplied to CR pin during master mode, and C and R pins must be left open.
2. Applies to the clock which is supplied to CL1 during slave mode. CR must be connected to GND,
and C and R pins must be left open.
3. Applies to the external clock which is supplied to CR during a master mode.
