Table 7.6
The number of execution states is calculated from using the formula below. Note that
of all transfers activated by one activation source (the number in which the CHNE bit is set to 1,
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 on-chip ROM to an internal I/O register, then the time required for the
DTC operation is 13 states. The time from activation to the end of data write is 10 states.
