10.7.1
An example is shown in which the DTC is used to receive 128 bytes of data via the SCI.
1. Set MRA to fixed source address (SM1 = SM0 = 0), incrementing destination address (DM1 =
2. Set the start address of the transfer information for an RXI interrupt at the DTC vector address.
3. Set the corresponding bit in DTCER to 1.
4. Set the SCI to the appropriate receive mode. Set the RIE bit in SCR to 1 to enable the receive
5. Each time reception of one byte of data ends on the SCI, the RDRF flag in SSR is set to 1, an
6. When CRA becomes 0 after the 128 data transfers have ended, the RDRF flag is held at 1, the
10.7.2
An example of DTC chain transfer is shown in which pulse output is performed using the PPG.
Chain transfer can be used to perform pulse output data transfer and PPG output trigger cycle
updating. Repeat mode transfer to the PPG's NDR is performed in the first half of the chain
transfer, and normal mode transfer to the TPU's TGR in the second half. This is because clearing
of the activation source and interrupt generation at the end of the specified number of transfers are
restricted to the second half of the chain transfer (transfer when CHNE = 0).

1, DM0 = 0), normal transfer mode (MD1 = MD0 = 0), and byte size (Sz1 = Sz0 = 0). The
DTS bit can have any value. Set MRB for one data transfer by one interrupt (CHNE = 0,
DISEL = 0). Set the RDR address of the SCI in SAR, the start address of the RAM area where
the data will be received in DAR, and 128 (H'0080) in CRA. CRB can be set to any value.
end (RXI) interrupt. Since the generation of a receive error during the SCI reception operation
will disable subsequent reception, the CPU should be enabled to accept receive error
interrupts.
RXI interrupt is generated, and the DTC is activated. The receive data is transferred from RDR
to RAM by the DTC. DAR is incremented and CRA is decremented. The RDRF flag is
automatically cleared to 0.
DTCE bit is cleared to 0, and an RXI interrupt request is sent to the CPU. Termination
processing should be performed in the interrupt handling routine.
