6.8
The following data transfers can be done using interrupt request signals:
• Activate DTC only; CPU interrupts depend on DTC settings
The INTC masks a CPU interrupt when the corresponding DTCE bit is 1. The conditions for
clearing DTCE and interrupt source flag are shown below.
DTCE clear condition = DTC transfer end • DTCECLR
Interrupt source flag clear condition = DTC transfer end • DTCECLR
where DTCECLR = DISEL + counter 0
Figures 6.5 and 6.6 show control block diagrams.
