942 / 1158 page ![]() Section 21 Flash Memory (0.18- µm F-ZTAT Version) Rev.1.00 Jun. 07, 2006 Page 890 of 1102 REJ09B0294-0100 (5) Flash Transfer Destination Address Register (FTDAR) FTDAR specifies the start address of the on-chip RAM at which to download an on-chip program. FTDAR must be set before setting the SCO bit in FCCS to 1. 7 TDER 0 R/W 6 TDA6 0 R/W 5 TDA5 0 R/W 4 TDA4 0 R/W 3 TDA3 0 R/W 0 TDA0 0 R/W 2 TDA2 0 R/W 1 TDA1 0 R/W Bit Bit Name Initial Value R/W Bit Bit Name Initial Value R/W Description 7 TDER 0 R/W Transfer Destination Address Setting Error This bit is set to 1 when an error has occurred in setting the start address specified by bits TDA6 to TDA0. A start address error is determined by whether the value set in bits TDA6 to TDA0 is within the range of H'00 to H'02 when download is executed 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 bits TDA6 to TDA0 should be within the range of H'00 to H'02. 0: The value specified by bits TDA6 to TDA0 is within the range. 1: The value specified by bits TDA6 to TDA0 is between H'03 and H'FF and download has stopped. 6 5 4 3 2 1 0 TDA6 TDA5 TDA4 TDA3 TDA2 TDA1 TDA0 0 0 0 0 0 0 0 R/W R/W R/W R/W R/W R/W R/W Transfer Destination Address Specifies the on-chip RAM start address of the download destination. A value between H'00 and H'02, and up to 4 kbytes can be specified as the start address of the on-chip RAM. H'00: H'FF9000 is specified as the start address. H'01: H'FFA000 is specified as the start address. H'02: H'FFB000 is specified as the start address. H'03 to H'7F: Setting prohibited. (Specifying a value from H'03 to H'7F sets the TDER bit to 1 and stops download of the on-chip program.) |
