Download Control

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 21.10.

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
