On setting of chain transfers using high-speed DTC transfers

Last Updated:01/16/2018

Question:

To perform high-speed DTC chain transfers, does only the control data for the high-speed DTC transfer of the SFR area need to be set?

Answer:

For high-speed DTC transfer, the transfer is executed based on the information from the high-speed dedicated control data of the SFR area. However, for chain transfer, data will be transferred by reading out the information of the control data in the RAM area.
Therefore, to execute high-speed DTC chain transfer, control data for both high-speed control data of the SFR area and the control data in the RAM area need to be set.
