• BUFF_LENGTH: Buffer Byte Length (Write-only)
This field determines the number of bytes to be transferred until end of buffer. The maximum channel transfer size
(64 KBytes) is reached when this field is 0 (default value). If the transfer size is unknown, this field should be set to 0, but
the transfer end may occur earlier under UDPHS device control.
When this field is written, The UDPHS_DMASTATUSx register BUFF_COUNT field is updated with the write value.
Notes:
6430D–ATARM–25-Mar-11
6430D–ATARM–25-Mar-11
1. Bits [31:2] are only writable when issuing a channel Control Command other than “Stop Now”.
2. For reliability it is highly recommended to wait for both UDPHS_DMASTATUSx register CHAN_ACT and CHAN_ENB flags
are at 0, thus ensuring the channel has been stopped before issuing a command other than “Stop Now”.
