Caution When rewriting TCL3 to other data, stop the serial transfer operation beforehand.
Remarks 1. fXX : Main system clock frequency (fX or fX/2)
2. fX: Main system clock oscillation frequency
3. MCS : Bit 0 of oscillation mode selection register (OSMS)
4. Figures in parentheses apply to operation with fX = 5.0 MHz.
