Description

ETH_RX / Timer2A

When set, indicates uDMA channel 6 is available and connected to the

receive path of the Ethernet module. If the corresponding bit in the

DMACHASGN register is set, the channel is connected instead to the

secondary channel assignment of Timer 2A.

USB_EP3_TX / Timer2B

When set, indicates uDMA channel 5 is available and connected to the

transmit path of USB endpoint 3. If the corresponding bit in the

DMACHASGN register is set, the channel is connected instead to the

secondary channel assignment of Timer 2B.

USB_EP3_RX / Timer2A

When set, indicates uDMA channel 4 is available and connected to the

receive path of USB endpoint 3. If the corresponding bit in the

DMACHASGN register is set, the channel is connected instead to the

secondary channel assignment of Timer 2A.

USB_EP2_TX / Timer3B

When set, indicates uDMA channel 3 is available and connected to the

transmit path of USB endpoint 2. If the corresponding bit in the

DMACHASGN register is set, the channel is connected instead to the

secondary channel assignment of Timer 3B.

USB_EP2_RX / Timer3A

When set, indicates uDMA channel 2 is available and connected to the

receive path of USB endpoint 2. If the corresponding bit in the

DMACHASGN register is set, the channel is connected instead to the

secondary channel assignment of Timer 3A.

USB_EP1_TX / UART2_TX

When set, indicates uDMA channel 1 is available and connected to the

transmit path of USB endpoint 1. If the corresponding bit in the

DMACHASGN register is set, the channel is connected instead to the

secondary channel assignment of UART module 2 transmit.

USB_EP1_RX / UART2_RX

When set, indicates uDMA channel 0 is available and connected to the

receive path of USB endpoint 1. If the corresponding bit in the

DMACHASGN register is set, the channel is connected instead to the

secondary channel assignment of UART module 2 receive.
