2.3 Using the ISP mode over RS232 interface
2.3.1 Baudrate
The maximum baudrate supported by the device depends on the crystal value or signal fre-
quency injected on XTAL1 pin. Refer to product datasheet for further information.
2.3.2 Hardware
The schematics of the interface are given here after.
Auto ISP feature: the implementation of this feature is optional.
When this feature is supported by the hardware, the same option can be activated in the prefer-
ences menu of FLIP. This option enables FLIP to manage and set automatically the hardware
condition to have the device run in ISP and to proceed with the part programming.
