1. MODCK1 pin = 0, MF = 1 ⇒ C
2. MODCK1 pin = 1, crystal is 32.768 kHz (or 4.192 MHz), initial MF = 401, initial frequency = 13.14 MHz,
3. MODCK1 pin = 1, crystal is 32.768 kHz (or 4.192 MHz), initial MF = 401, initial frequency = 13.14 MHz,
4. In order to get higher range, higher crystal frequency can be used (i.e. 50 kHz), in this case:
