On-Chip Peripheral Module Request Mode
In this mode, a transfer is performed at the transfer request signal of an on-chip peripheral module.
Transfer request signals comprise the transmit data empty transfer request and receive data full
transfer request from the ADC set by CHCR0 to CHCR5 and the SCIF0, SCIF1, MMC, USBF,
SIM, SIOF0, SIOF1, and SDHI set by DMARS0/1/2, and the compare-match timer transfer
request from the CMT (channels 0 to 4).
When this mode is selected, if the DMA transfer is enabled (DE = 1, DME = 1, TE = 0, AE = 0,
NMIF = 0), a transfer is performed upon the input of a transfer request signal.
When a transmit data empty transfer request of the SCIF0 is set as the transfer request, the transfer
destination must be the SCIF0's transmit data register. Likewise, when receive data full transfer
request of the SCIF0 is set as the transfer request, the transfer source must be the SCIF0's receive
data register. These conditions also apply to the SIOF1, MMC, USBF, SIM, SIOF0, SIOF1, and
SDHI. When the ADC is set as the transfer request, the transfer source must be the A/D data
register. Any address can be specified for data source and destination, when transfer request is
generated by the CMT (channels 0 to 4).
The number of the receive FIFO triggers can be set as a transfer request depending on an on-chip
peripheral module. Data needs to be read after the DMA transfer is ended, because data may be
remained in the receive FIFO when the receive FIFO trigger condition is not satisfied.
