To program the UPM with the memory profile for the MSC8101 system bus-to-HDI16 interface, the
single-beat read and write entries are as listed in Table 2. All other values in the array representing bursts
and periodic timers are not required, and you can set them to 0xFFFFFFFF (or 0xFFFFFCFF) to disable
them.
NOTE: The txx numbers refer to the MSC8101 timing specification. For details, see the MSC8101
