These bits should be cleared to 0.
Frequency Set
These bits set the operating frequency of the CPU. The
setting value must be calculated as follows:
1. Round off the operating frequency expressed in MHz
2. Multiply the rounded number by 100 and convert the
For example, when the operating frequency of the CPU
is 20.000 MHz, the setting value is as follows:
1. Round 20.000 off at the third decimal place as
2. Convert 20.00 × 100 = 2000 into a binary number
unit at the third decimal place to make it into two
decimal places.
