Section 7 Data Transfer Controller (DTC)
The EVENTI interrupt request activates the DTC and transfers data from RAM to RAM in the
same address. Data is incremented in the DTC. The lower five bits of SAR and DAR are replaced
with address code that is generated by the ECS flag status.
When the DTC transfer is completed, the ECS flag for transfer is cleared.
