Bandwidth History Register n
The SWU bandwidth history registers (SWU_HIST[n]) contain data copied from a watchpoint group's current
bandwidth value (SWU_CUR[n]
ods. At the end of each watchpoint period, the SWU copies the previous bandwidth value from the
SWU_HIST[n].BWHIST0 field to the SWU_HIST[n].BWHIST1 field and copies the new bandwidth value
from the SWU_CUR[n].CURBW field to the SWU_HIST[n].BWHIST0 field.
