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 and enables the user branch function.

Description
Set to H'AA55 if the user branch function is enabled by
the flash user branch enable bit. Otherwise, set to
H'0000.
Frequency Set
Set the operating frequency of the CPU. 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 35.000 MHz, the value is as follows.
1. The number to three decimal places of 35.000 is
2. The formula that 35.00 × 100 = 3500 is converted to
