13.4.2
Figure 13.3 shows an example in which the 8-bit timer is used to generate a pulse output with a
selected delay in response to the TMRI input. The control bits are set as follows:
[1] The CCLR0 bit in TCR is set to 1 and the TMRIS bit in TCCR is set to 1 so that TCNT is
[2] In TCSR, bits OS3 to OS0 are set to B'0110, causing the output to change to 1 at a TCORA
With these settings, the 8-bit timer provides output of pulses whose delay from the TMRI input is
determined by TCORA and the pulse width determined by (TCORB − TCORA).
