4.2.4.2 RX Flow N Configuration Register B (0x004 + 32×N)
The RX Flow N Configuration Register B contains static configuration information for the RX DMA flow. The fields in this register can be safely changed only when all of the DMA channels that use this flow have been disabled. The fields in this register are shown in Figure 4-28:

Description |
31-24 |
RX_SRC_TAG_HI |
RX Source Tag High Byte Constant Value: This is the value to insert into bits 15-8 of the source tag if the RX_SRC_TAG_HI_SEL is set to 1. |
23-16 |
RX_SRC_TAG_LO |
RX Source Tag Low Byte Constant Value: This is the value to insert into bits 7-0 of the source tag if the RX_SRC_TAG_LO_SEL is set to 1. |
15-8 |
RX_DEST_TAG_HI |
RX Destination Tag High Byte Constant Value: This is the value to insert into bits 15-8 of the destination tag if the RX_DEST_TAG_HI_SEL is set to 1. |
7-0 |
RX_DEST_TAG_LO |
RX Destination Tag Low Byte Constant Value: This is the value to insert into bits 7-0 of the destination tag if the RX_DEST_TAG_LO_SEL is set to 1. |
