[2] Perform settings for transfer to the TPU’s TGR. Set MRA to source address incrementing
[3] Locate the TPU transfer register information consecutively after the NDR transfer register
[4] Set the start address of the NDR transfer register information to the DTC vector address.
[5] Set the bit corresponding to TGIA in DTCER to 1.
[6] Set TGRA as an output compare register (output disabled) with TIOR, and enable the TGIA
[7] Set the initial output value in PODR, and the next output value in NDR. Set bits in DDR and
[8] Set the CST bit in TSTR to 1, and start the TCNT count operation.
[9] Each time a TGRA compare match occurs, the next output value is transferred to NDR and the
[10] When the specified number of transfers are completed (the TPU transfer CRA value is 0), the
(3) Software Activation
An example is shown in which the DTC is used to transfer a block of 128 bytes of data by means
of software activation. The transfer source address is H'1000 and the destination address is
H'2000. The vector number is H'60, so the vector address is H'04C0.
[1] Set MRA to incrementing source address (SM1 = 1, SM0 = 0), incrementing destination
chain mode (CHNE = 1, DISEL = 0). Set the data table start address in SAR, the NDRH
address in DAR, and the data table size in CRAH and CRAL. CRB can be set to any value.
(SM1 = 1, SM0 = 0), fixed destination address (DM1 = DM0 = 0), normal mode (MD1 = MD0
= 0), and word size (Sz = 1). Set the data table start address in SAR, the TGRA address in
DAR, and the data table size in CRA. CRB can be set to any value.

interrupt with TIER.
NDER for which output is to be performed to 1. Using PCR, select the TPU compare match to
be used as the output trigger.
set value of the next output trigger period is transferred to TGRA. The activation source TGFA
flag is cleared.
TGFA flag is held at 1, the DTCE bit is cleared to 0, and a TGIA interrupt request is sent to the
CPU. Termination processing should be performed in the interrupt handling routine.
address (DM1 = 1, DM0 = 0), block transfer mode (MD1 = 1, MD0 = 0), and byte size (Sz =
0). The DTS bit can have any value. Set MRB for one block transfer by one interrupt (CHNE =
0). Set the transfer source address (H'1000) in SAR, the destination address (H'2000) in DAR,
and 128 (H'8080) in CRA. Set 1 (H'0001) in CRB.
