These are read-only bits and cannot be modified.
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 or
FECS is automatically downloaded in the on-chip RAM
area specified by FTDAR.
In order to set this bit to 1, the RAM emulation mode
must be canceled, H'A5 must be written to FKEY, and
this operation must be executed in the on-chip RAM.
Dummy read of FCCS must be executed twice
immediately after setting this bit to 1. All interrupts must
be disabled during download. This bit is cleared to 0
when download is completed.
During program download initiated with this bit,
particular processing which accompanies bank-
switching of the program storage area is executed.
Before a download request, initialize the VBR contents
to H'00000000. After download is completed, the VBR
contents can be changed.
