Bit 14—Full Address Enable 0 (FAE0): Specifies whether channel 0 is to be used in short
address mode or full address mode.
In short address mode, channels 0A and 0B can be used as independent channels.
Bit 14
FAE0 Description
0 Short address mode (Initial value)
1 Full address mode
Bit 13—Single Address Enable 1 (SAE1): Specifies whether channel 1B is to be used for
transfer in dual address mode or single address mode.
This bit is invalid in full address mode.
Bit 13
SAE1 Description
0 Transfer in dual address mode (Initial value)
1 Transfer in single address mode
Bit 12—Single Address Enable 0 (SAE0): Specifies whether channel 0B is to be used for
transfer in dual address mode or single address mode.
This bit is invalid in full address mode.
Bit 12
SAE0 Description
0 Transfer in dual address mode (Initial value)
1 Transfer in single address mode
Bits 11 to 8—Data Transfer Acknowledge (DTA): These bits enable or disable clearing, when
DMA transfer is performed, of the internal interrupt source selected by the data transfer factor
setting.
When DTE = 1 and DTA = 1, the internal interrupt source selected by the data transfer factor
setting is cleared automatically by DMA transfer. When DTE = 1 and DTA = 1, the internal
interrupt source selected by the data transfer factor setting does not issue an interrupt request to the
CPU or DTC.
