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. Since the user branch function is supported, the
user branch destination address must be set.
The initial program is set as a parameter of the programming/erasing program which has
downloaded these settings.
This parameter sets the operating frequency of the CPU.
For the range of the operating frequency of this LSI, see section 26.3.1, Clock Timing.
