Chain Transfer: 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] Perform settings for transfer to the PPG’s NDR. Set MRA to source address incrementing
[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

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. Wrap-up processing should be performed in the interrupt handling routine.
