Programming/Erasing Initialization: The on-chip programming/erasing program to be
downloaded includes the initialization program.
The specified period pulse must be applied when programming or erasing. The specified pulse
width is made by the method in which wait loop is configured by the CPU instruction. The
operating frequency of the CPU must be set.
The initial program is set as a parameter of the programming/erasing program which has
downloaded these settings.
a Flash programming/erasing frequency parameter (FPEFEQ: general register ER0 of CPU)
This parameter sets the operating frequency of the CPU. The settable range of the operating
frequency in this LSI is 10 to 33 MHz.

Frequency Set
Set the operating frequency of the CPU. With the PLL
multiplication function, set the frequency multiplied. The
setting value must be calculated as the following
methods.
1. The operating frequency which is shown in MHz
2. The value multiplied by 100 is converted to the
For example, when the operating frequency of the CPU
is 33.000 MHz, the value is as follows.
1. The number to three decimal places of 33.000 is
2. The formula that 33.00 × 100 = 3300 is converted to
