cycle type. RUN commands (MxMR[OP] = 11), however, can initiate patterns starting at any of the 64
UPM RAM words.
13.4.4.1.1
The user must ensure that the UPM is appropriately initialized before a request occurs.
The UPM supports two types of memory reads and writes:
The user must ensure that patterns for single-beat transfers contain one, and only one, transfer
acknowledge (UTA bit in RAM word set high) and for a burst transfer, contain the exact number of transfer
acknowledges required.

•
A single-beat transfer transfers one operand consisting of up to a single word (dependent on port
size). A single-beat cycle starts with one transfer start and ends with one transfer acknowledge.
A burst transfer transfers exactly 4 double words regardless of port size. For 32-bit accesses, the
burst cycle starts with one transfer start but ends after eight transfer acknowledges, whereas an
8-bit device requires 32 transfer acknowledges.
