(6) Flash Transfer Destination Address Register (FTDAR)
FTDAR specifies the on-chip RAM address to which the on-chip program is downloaded. Make
settings for FTDAR before writing 1 to the SCO bit in FCCS. The initial value is H'00 which
points to the start address (H'FFBC00) in on-chip RAM.
Bit 7—Transfer Destination Address Setting Error: This bit is set to 1 when there is an error in
the download start address set by bits 6 to 0 (TDA6 to TDA0). Whether the address setting is
erroneous or not is judged by checking whether the setting of TDA6 to TDA0 is between the range
of H'00 and H'03 after setting the SCO bit in FCCS to 1 and performing download. Before setting
the SCO bit to 1 be sure to set the FTDAR value between H'00 to H'03 as well as clearing this bit
to 0.

Bits 6 to 0—Transfer Destination Address (TDA6 to TDA0): These bits specify the download
start address. A value from H'00 to H'03 can be set to specify the download start address in on-
chip RAM in 4-kbyte units.
A value from H'04 to H'7F cannot be set. If such a value is set, the TDER bit (bit 7) in this register
is set to 1 to prevent download from being executed.
