Table 7.9
The number of execution states is calculated from the formula below. Note that
of all transfers activated by one activation event (the number for which the CHNE bit is set to one,
plus 1).
For example, when the DTC vector address table is located in on-chip ROM, normal mode is set,
and data is transferred from the on-chip ROM to an internal I/O register, the time required for the
DTC operation is 13 states. The time from activation to the end of the data write is 10 states.
