• Flash Transfer Destination Address Register (FTDAR)
FTDAR is a register that specifies the address to download an on-chip program. This register must
be specified before setting the SCO bit in FCCS to 1.

R/W Transfer Destination Address Setting Error
This bit is set to 1 when the address specified by bits
TDA6 to TDA0, which is the start address to download an
on-chip program, is over the range. Whether or not the
range specified by bits TDA6 to TDA0 is within the range
of H'00 to H'03 is determined when an on-chip program is
downloaded by setting the SCO bit in FCCS to 1. Make
sure that this bit is cleared to 0 before setting the SCO bit
to 1 and the value specified by TDA6 to TDA0 is within
the range of H'00 to H'03.
0: The value specified by bits TDA6 to TDA0 is within the
range.
1: The value specified by is TDA6 to TDA0 is over the
range (H'04 to H'FF) and the download is stopped.

H'02: H'FF1800 is specified as a start address to
download an on-chip program.
H'03: H'FF8800 is specified as a start address to
