Description
Source Program Copy Operation
Requests the on-chip programming/erasing program to
be downloaded to the on-chip RAM.
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 area specified by FTDAR.
In order to set this bit to 1, H'A5 must be written to
FKEY and this operation must be in the on-chip RAM.
Four NOP instructions must be executed immediately
after setting this bit to 1.
For interrupts during download, see section 17.7.1,
Interrupts during Programming/Erasing. For the
download time, see section 17.7.2, Other Notes.
Since this bit is cleared to 0 when download is
completed, this bit cannot be read as 1.
Download by setting the SCO bit to 1 requires a special
interrupt processing that performs bank switching to the
on-chip program storage area. Therefore, before
issuing a download request (SCO = 1), set VBR to
H'84000000. Otherwise, the CPU gets out of control.
Once download end is confirmed, VBR can be changed
to any other value.
The mode in which the FWE pin is high must be used
when using the SCO function.
