Buffer operation, enables TGRC and TGRD to be used as buffer registers.
Table 15.6 shows the register combinations used in buffer operation.
Table 15.6 Register Combinations in Buffer Operation
When a compare match occurs, the value in the buffer register for the corresponding channel is
transferred to the timer general register. For update timing from a buffer register, rewriting on
compare match occurrence or on counter cleaning can be selected.
This operation is illustrated in figure 15.8.
