Description
Data Transfer End Interrupt Enable 1A
Enables or disables an interrupt to the CPU or
DTC when transfer ends. If the DTE1 bit is cleared
to 1 when DTIE1A = 1, the DMAC regards this as
indicating the end of a transfer, and issues a
transfer end interrupt request to the CPU or DTC.
A transfer end interrupt can be canceled either by
clearing the DTIE1A bit to 0 in the interrupt
handling routine, or by performing processing to
continue transfer by setting the transfer counter
and address register again, and then setting the
DTE1 bit to 1.
Data Transfer Interrupt Enable 0B
Enables or disables an interrupt to the CPU or
DTC when transfer on channel 1 is interrupted. If
the DTME0 bit is cleared to 0 when DTIE0B = 1,
the DMAC regards this as indicating a break in the
transfer, and issues a transfer break interrupt
request to the CPU or DTC.
A transfer break interrupt can be canceled either
by clearing the DTIE0B bit to 0 in the interrupt
handling routine, or by performing processing to
continue transfer by setting the DTME0 bit to 1.
Data Transfer End Interrupt Enable 0A
Enables or disables an interrupt to the CPU or
DTC when transfer ends. If the DTE0 bit is cleared
to 0 when DTIE0A = 1, the DMAC regards this as
indicating the end of a transfer, and issues a
transfer end interrupt request to the CPU or DTC.
A transfer end interrupt can be canceled either by
clearing the DTIE0A bit to 0 in the interrupt
handling routine, or by performing processing to
continue transfer by setting the transfer counter
and address register again, and then setting the
DTE0 bit to 1.
