FLASH PROGRAM MEMORY (Cont’d)
4.4 ICP (In-Circuit Programming)
To perform ICP the microcontroller must be
switched to ICC (In-Circuit Communication) mode
by an external controller or programming tool.
Depending on the ICP code downloaded in RAM,
Flash memory programming can be fully custom-
ized (number of bytes to program, program loca-
tions, or selection serial communication interface
for downloading).
When using an STMicroelectronics or third-party
programming tool that supports ICP and the spe-
cific microcontroller device, the user needs only to
implement the ICP hardware interface on the ap-
plication board (see Figure 9). For more details on
the pin locations, refer to the device pinout de-
scription.
ICP needs six signals to be connected to the pro-
gramming tool. These signals are:
–VSS: device power supply ground
–VDD: for reset by LVD
– OSCIN: to force the clock during power-up
– ICCCLK: ICC output serial clock pin
– ICCDATA: ICC input serial data pin
–VPP: ICC mode selection and programming
voltage.
If ICCCLK or ICCDATA are used for other purpos-
es in the application, a serial resistor has to be im-
plemented to avoid a conflict in case one of the
other devices forces the signal level.
Note: To develop a custom programming tool, re-
fer to the ST7 FLASH Programming and ICC Ref-
erence Manual which gives full details on the ICC
protocol hardware and software.
4.5 IAP (In-Application Programming)
This mode uses a BootLoader program previously
stored in Sector 0 by the user (in ICP mode or by
plugging the device in a programming tool).
This mode is fully controlled by user software. This
allows it to be adapted to the user application, (us-
er-defined strategy for entering programming
mode, choice of communications protocol used to
fetch the data to be stored, etc.). For example, it is
possible to download code from the USB interface
and program it in the Flash. IAP mode can be used
to program any of the Flash sectors except Sector
0, which is write/erase protected to allow recovery
in case errors occur during the programming oper-
ation.
