When this bit is set to 1, the on-chip program which is
selected by FPCS/FECS is automatically downloaded in
the on-chip RAM specified by FTDAR.
In order to set this bit to 1, H′A5 must be written to FKEY
and this operation must be executed in the on-chip RAM.
Four NOP instructions must be executed immediately
after setting this bit to 1.
Since this bit is cleared to 0 when download is
completed, this bit cannot be read as 1.
All interrupts must be disabled. This should be made in
the user system.
0: Download of the on-chip programming/erasing
program to the on-chip RAM is not executed.
