NOTES:

When the TMOD bit is set to 0 (input capture mode), set bits CCLR, and TRFC14 to TRFC17 to 0.

When the TSTART bit in the TRFCR0 register is set to 0 (count stops), rew rite bits CCLR and TMOD.

When the TMOD bit is set to 0 (input capture mode), set bits ILVL2 to ILVL0 in the CMP1IC register to 000b (level 0)

and set the IR bit to 0 (no interrupt requested).
