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 where an on-
chip program is downloaded, is over the range. Whether
or not the address specified by bits TDA6 to TDA0 is
within the range of H'00 to H'02 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 and the
value specified by bits TDA6 to TDA0 is within the range
of H'00 to H'02 before setting the SCO bit to 1.
