6.3.5 PC Break Operation in Continuous Data Transfer
If a PC break interrupt is generated when the following operations are being performed, exception
handling is executed on completion of the specified transfer.
(1) When a PC break interrupt is generated at the transfer address of an EEPMOV.B instruction:
PC break exception handling is executed after all data transfers have been completed and the
EEPMOV.B instruction has ended.
(2) When a PC break interrupt is generated at a DTC transfer address:
PC break exception handling is executed after the DTC has completed the specified number of
data transfers, or after data for which the DISEL bit is set to 1 has been transferred.
