Description
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'01 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'01.
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'02 and H'FF and download has stopped.
Transfer Destination Address
Specifies the on-chip RAM start address of the
download destination. A value between H'00 and H'01,
and up to 3 kbytes can be specified as the start address
of the on-chip RAM.
H'00:
H'FFD080 is specified as the start
address.
H'01:
H'FFD880 is specified as the start
address.
H'02 to H'7F: Setting prohibited
(Specifying a value from H'02 to H'7F sets
the TDER bit to 1 and stops download of
the on-chip program.)
