CHAPTER 4 RESET
Figure 4.4-2 Transfer of reset vectors and mode data
Reference:
Use a mode pin, from which reset vectors and mode data are read, to specify either internal
ROM or external memory. If the external vector mode is specified with a mode pin, however,
external memory and not internal ROM is accessed to read reset vectors and mode data.
Fujitsu recommends specifying the internal vector mode with a mode pin when the single-
chip mode and internal ROM external bus mode are used.
❍
Mode data (Address: FFFFDF
H
)
The data in the mode register can be modified only by a reset, and the mode register settings
become effective after a reset. Refer to Section "7.3 Mode Data", for details on mode data.
❍
Reset vector (Address: FFFFDC
H
to FFFFDE
H
)
Write the execution start address after the end of a reset. Execution starts from this address.
