Value
Value
Value
Byte value that, if matched, will terminate a buffer.
Mask for termination byte. A one in a bit position enables the corresponding bit
of the termination byte to be used in the compare to generate the termination
condition. A zero in a bit position disables the corresponding bit from
contributing to the termination condition. A value of all zeros in this register
disables the termination-byte match feature.
Bits 7:0 of the buffer unused length value are stored in this register. The DMA
copies the buffer remaining length to this register at the completion of the
transfer. Normally the buffer remaining length is zero, but if the transfer
terminates early, under source control or because of a termination-byte match,
the number of unused bytes in the buffer is written.
