(2) 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.
