Settings Of The Start91460.Asm; Controller Device (Device); Boot / Flash Security (Boot_Flash_Sec) - Fujitsu FR Series Application Note

2 Settings of the Start91460.asm

The startup file has to be configured for the target system (hardware) and the application
software. The startup file provides several prepared settings, which have to be checked and
which have possibly to be changed. The header of the startup file contains information how
to find the lines containing the options to be checked. All lines with the comment extension
"<<<" were pointing to available settings.
In the following paragraphs all available settings are described.

2.1 Controller Device (DEVICE)

Set the target device the application is running in. This setting is used by the startup file to
check the availability of registers and to check the plausibility of settings.
Available settings for DEVICE:
- MB91464A
- MB91467B
- MB91467C
- MB91467D
- MB91469G
- MB91465K
- MB91463N
- MB91461R
- MB91467R
- MB91465X
- others
Note: This list will be adapted, depending on new devices
Note: The setting "others" should only be used for the case that desired device of the
MB91460 Series is not listed.
Example:
The target controller is the MB91F467DA. This requires the setting.
#set DEVICE

2.2 Boot / Flash Security (BOOT_FLASH_SEC)

The most flash devices have two flash and two boot security vectors. It is important to set
the four vectors correctly. Valid boot security vectors means that the build-in bootrom can
not be entered anymore.
Available settings for BOOT_FLASH_SEC:
- OFF: The security feature is switched off. The section SECURITY_VECTORS is reserved
and the vectors are set to 0xFFFFFFFF.
- ON: The security vectors are not set. But the section SECURITY_VECTORS is reserved.
The security vectors have to be set in the user application.
Note: This feature is not available for all devices of the MB91460 Series. The datasheet of
the target device lists the available features.
Note: If the device MB91469G is selected, the section SECURITY_VECTORS is located
from 0x24:8000 – 0x24:800F.
Note: If the ROMless device MB91461R is selected no section SECURITY_VECTORS is
reserved.
