TSCALE stores a scaling value that is one less than the number of cycles
between decrements of TCOUNT. For example, if the value in TSCALE
register is 0, the counter register decrements once every cycle. If the value
in TSCALE is 1, the counter decrements once every 2 cycles. Figure 6.2
shows the timer block diagram.
