+To get hundredths of MHz the rate needs to be divided by 10'000.
+Here is an example:
+ twd_timer_rate = 123456789
+ Before the patch:
+    twd_timer_rate / 1000000 = 123
+    (twd_timer_rate / 1000000) % 100 = 23
+    Result: 123.23MHz.
+ After being fixed:
+    twd_timer_rate / 1000000 = 123
+    (twd_timer_rate / 10000) % 100 = 45
+    Result: 123.45MHz.
