FLASH PROGRAM MEMORY (Cont’d)
4.5 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 6). For more details on
the pin locations, refer to the device pinout de-
scription.
ICP needs seven pins to be connected to the pro-
gramming tool. These pins are:
– RESET: device reset
–VSS: device power supply ground
– ICCCLK: ICC output serial clock pin
– ICCDATA: ICC input serial data pin
– ICCSEL/VPP: programming voltage
– OSC1: main clock input for external source
–VDD: application board power supply
CAUTIONS:
1. If RESET, ICCCLK or ICCDATA pins are used
for other purposes in the application, a serial resis-
tor has to be implemented to avoid a conflict in
case one of the other devices forces the signal lev-
el. If these pins are used as outputs in the applica-
tion, the serial resistors are not necessary.
2. As soon as the external controller is plugged to
the board, even if an ICC session is not in
progress, the ICCCLK and ICCDATA pins are not
available for the application.
Note: To develop a custom programming tool, re-
fer to the ST7 ICC Reference Manual which gives
full details on the ICC protocol hardware and soft-
ware.
