Access states
The number of execution states is calculated from the formula below. Note that Σ means the sum
of all transfers activated by one activation event (the number in which the CHNE bit is set to 1,
plus 1).
Number of execution states = I · (S
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 14 states. The time from activation to the end of the data write is 11 states.
