TCNR is a 16-bit readable/writable register that enables or disables connection between the channel 8 down-count start
register (DSTR) and channel 1 and 2 compare-match signals (down-count start triggers). Channel 1 down-count start
triggers A to H are channel 1 OCR1 compare-match signals or GR1x compare-match signals (set in TRGMDR). Channel
2 down-count start triggers A to H are channel 2 OCR2x compare-match signals. When GR1x compare-matches are used,
set TIOR1A to TIOR1D to allow compare-matches.
TCNR is initialized to H'0000 by a power-on reset, and in hardware standby mode and software standby mode.
For details, see sections 11.3.5, One-Shot Pulse Function, and 11.3.6, Offset One-Shot Pulse Function and Output Cutoff
Function.
