In X-Y FIFO mode, the static TR consists of the following information.
Param | PSIL Addr | Field | Description |
---|---|---|---|
Burst | 0x400 | 31 | When set, enables VBUSP burst mode on this channel. See the XY burst description for more information. |
Acc32 | 0x400 | 30 | When set, enables 32-bit access mode. On a 32-bit PDMA, all accesses will have XCNT=4 to support legacy IP that is not fully VBUSP compliant. This bit is ignored if the PDMA VBUSP port is not 32 bits wide. |
X | 0x400 | 26:24 | Element size. This field specifies how much data is transferred in each write which is performed by the DMA. This field is encoded as follows: 0 = 8 bits, 1 = 16 bits, 2 = 24 bits, 3 = 32 bits, 4 = 64 bits, and 5-7 = RESERVED |
Y | 0x400 | 11:0 | Element count. This field specifies how many elements to transfer each time a trigger is received on the channel. |
EOL | 0x401 | 31 | EOL Mode. Normally, when the Z count of FIFO operations has been reached, the PDMA will close the packet with an 'EOP' indication. When this flag is set, the PDMA will instead trigger an EOL at the completion of Z. |
Z | 0x401 | 23:0 | FIFO count. This field specifies how many full FIFO operations comprise a complete packet. When the count has been reached, the PDMA will close the packet with an 'EOP' indication. If this parameter is set to NULL, then no packet delineation is supplied by the PDMA and all framing is controlled via the UDMA-P TR. |
