Section 7 Data Transfer Controller [H8S/2138 Group]
7.3.8
Setting the CHNE bit to 1 enables a number of data transfers to be performed consecutively in
response to a single transfer request. SAR, DAR, CRA, CRB, MRA, and MRB, which define data
transfers, can be set independently.
Figure 7.9 shows memory mapping for chain transfer.
In the case of transfer with CHNE set to 1, an interrupt request to the CPU is not generated at the
end of the specified number of transfers or by setting of the DISEL bit to 1, and the interrupt
source flag for the activation source is not affected.
