5. Example of Buffer Operation Setting Procedure
When the counter switches from counting up to counting down or vice versa, the value of the
buffer register is transferred to the general register. Here, the value of the buffer register is
transferred to the general register in the following timing:
A. When TCNT_0 and GRA_0 are compared and their contents match
B. When TCNT_1 underflows
The value of the buffer register is transferred from compare match A0 to the general register.
Figure 13.37 shows an example of the buffer operation setting procedure.
