Description
Unused
These bits should be cleared to 0.
Frequency Set
These bits set the operating frequency of the CPU.
When the PLL multiplication function is used, set the
multiplied frequency. The setting value must be
calculated as follows:
1. The operating frequency shown in MHz units must be
2. The value multiplied by 100 is converted to the binary
For example, when the operating frequency of the CPU
is 35.000 MHz, the value is as follows:
1. The number of three decimal places of 35.000 is
2. The formula of 35.00 × 100 = 3500 is converted to the
rounded in a number of three decimal places and be
shown in a number of two decimal places.
