Bit Name
Reset R/W Description
7:5 DIV[2:0]
000
R/W Prescaler divider value. Generates the active clock edge used to update the
counter as follows:
000 Tick frequency /1
001 Tick frequency /2
010 Tick frequency /4
011 Tick frequency /8
100 Tick frequency /16
101 Tick frequency /32
110 Tick frequency /64
111 Tick frequency /128
Note: Changes to these bits has immediate effect on the frequency of the active
