FLASH PROGRAM MEMORY (Cont’d)
Figure 4. Typical ICC Interface
ICP needs a minimum of 4 and up to 6 pins to be
connected to the programming tool. These pins
are:
– RESET: device reset
–VSS: device power supply ground
– ICCCLK: ICC output serial clock pin
– ICCDATA: ICC input serial data pin
– CLKIN: 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. As
soon as the external controller is plugged to the
board, the ICCCLK and ICCDATA pins cannot be
used for other purposes.
2. If the OSC option bit (RC oscillator selection) is
set unintentionally, an external clock must be pro-
vided via CLKIN to reprogram the device via ICP
(the ST7 clock has to be running).
3. The use of Pin 7 of the ICC connector depends
on the Programming Tool architecture. Please re-
fer to the documentation of the tool. This pin must
be connected when using ST Programming Tools
(it is used to monitor the application power supply).
4.5 Register Description
FLASH CONTROL/STATUS REGISTER (FCSR)
Read/Write
Reset Value: 000 0000 (00h)
1st RASS Key: 0101 0110 (56h)
2nd RASS Key: 1010 1110 (AEh)
Note: This register is reserved for programming
using ICP, IAP or other programming methods.
For details on XFlash programming, refer to the
ST7 Flash Programming Reference Manual.
When an EPB or another programming tool is
used (in socket or ICP mode), the RASS keys are
sent automatically.
