downloaded in three separate packets. To download the three
packets, you can either send three separate block transfer write

set up one BTW and BTR pair and move the data for each of the
packets into the BTW statement after the preceding packet has been
sent and received.
Note: If less than 32 events are in the packet, the rest of the event
data is padded with zeros.
