2.10 ISaGRAF Start Flag
The command si can be used to display / change the setting of the ISaGRAF Start Flag. Valid values are 0 and 1.
See pep-vdme.wri on ISaGRAF Workbench for more information about the usage of this flag.
Note: The ISaGRAF Start Flag is stored in the boot section of the serial EEPROM or RTC. This section is validated with
a CRC code to avoid the setting of random parameters. If the CRC of the Boot section is not valid, changing the ISaGRAF
Start Flag has no effect because the bw command does not validate an invalid CRC to avoid undesired side effects. In this
case, the default of 5 seconds is always used. On CPU equipped with a RTC which holds the ISaGRAF Start Flag there is
no CRC value included.
Note: The setting of this flag has no influence on the behaviour of the Bootstrap Loader.
2.11 Example using Hyperterminal from Windows 95 ® or Windows NT ®
The host is assumed to be a PC with Windows 95 or Windows NT. A serial cable is used to connect the term port of the
board to program to COM2 of the PC. Additionally, we assume that we want to program a MOTOROLA S-record built
for the FLASH address of the board. The serial connection runs at the default configuration of 9600 baud with no parity
and one stopbit. The properties should look like the following:
