Notes:
After Reset
1. Enabled when the ITCLKi bit in the TRDECR register is set to 0 (TRDCLK input) and the STCLK bit in the
2. Enabled when the ITCLKi bit in the TRDECR register is set to 1 (fC2) in timer mode.
3. Set bits TCK2 to TCK0 and bits CKEG1 to CKEG0 in registers TRDCR0 and TRDCR1 to the same values.
4. Enabled when bits TCK2 to TCK0 are set to 101b (TRDCLK input or fC2), the ITCLKi bit in the TRDECR is set to
5. To select fOCO-F, set it to the clock frequency higher than the CPU clock frequency.
