Stellaris^® LM3S1651 Microcontroller
Register 24: Device Capabilities 7 (DC7), offset 0x028
This register is predefined by the part and can be used to verify uDMA channel features. A 1 indicates
the channel is available on this device; a 0 that the channel is only available on other devices in the
family. Most channels have primary and secondary assignments. If the primary function is not
available on this microcontroller, the secondary function becomes the primary function. If the
secondary function is not available, the primary function is the only option.

Description
Reserved
Reserved for uDMA channel 31.
SW
When set, indicates uDMA channel 30 is available for software transfers.
I2S0_TX / CAN1_TX
When set, indicates uDMA channel 29 is available and connected to
the transmit path of I2S module 0. If the corresponding bit in the
DMACHASGN register is set, the channel is connected instead to the
secondary channel assignment of CAN module 1 transmit.
I2S0_RX / CAN1_RX
When set, indicates uDMA channel 28 is available and connected to
the receive path of I2S module 0. If the corresponding bit in the
DMACHASGN register is set, the channel is connected instead to the
secondary channel assignment of CAN module 1 receive.
CAN1_TX / ADC1_SS3
When set, indicates uDMA channel 27 is available and connected to
the transmit path of CAN module 1. If the corresponding bit in the
DMACHASGN register is set, the channel is connected instead to the
secondary channel assignment of ADC module 1 Sample Sequencer
3.
CAN1_RX / ADC1_SS2
When set, indicates uDMA channel 26 is available and connected to
the receive path of CAN module 1. If the corresponding bit in the
DMACHASGN register is set, the channel is connected instead to the
secondary channel assignment of ADC module 1 Sample Sequencer
