DMA Controller (DMAC)
The DMA controller is a module embedded in FR family devices, and performs DMA (direct memory access)
transfer.
DMA transfer performed by the DMA controller transfers data without intervention of CPU, contributing to en-
hanced performance of the system.
8 channels
Mode : single/block transfer, burst transfer and continuous transfer : 3 kinds of transfer
Transfer all through the area
Max. 65536 of transfer cycles
Interrupt function right after the transfer
Selectable for address transfer increase/decrease by the software
External transfer request input pin, external transfer request accept output pin, external transfer complete
output pin three pins for each
