The on-chip program is automatically downloaded by setting the SCO bit to 1. The on-chip
RAM area to be downloaded is the area as much as 3 Kbytes starting from the start address
specified by FTDAR. For the address map of the on-chip RAM, see figure 22.10.
The download control is set by using the programming/erasing interface registers. The return
value is given by the DPFR parameter.
(a) Download pass/fail result parameter (DPFR: one byte of start address of on-chip RAM
specified by FTDAR)
This parameter indicates the return value of the download result. The value of this
parameter can be used to determine if downloading is executed or not. Since the
confirmation whether the SCO bit is set to 1 is difficult, the certain determination must be
performed by setting one byte of the start address of the on-chip RAM area specified by
FTDAR to a value other than the return value of download (for example, H'FF) before the
download start (before setting the SCO bit to 1). For the checking method of download
results, see section 22.5.2 (2), Programming Procedure in User Program Mode.
