Device specific information
4. In the ST7FLITEUS, an interrupt is generated in ICC mode due to ICCCLK on PA1, configured as pull-up interrupt by
5. Contrary to the behavior described in “appli clock” legend, the ST7FLITEUS takes into account the option byte
6. There are 4 option bytes in this device: Option byte 0 and 1 starting at address E000h and Option byte 2 and 3 starting at
7. The pulse counter is reset when RESET and ICCSEL are both low.
8. If ICC mode is entered using this pulse sequence, the clock source option bits must not be modified during the ICC
9. All ROM devices support the medium variant of the ICC monitor. Hence these devices can be read if the Read-out
10. For these devices, if this number of pulses is generated, the ST7 can be supplied by an external clock source or a

default. The workaround is to enable the interrupt mask before the IRET of the ICC monitor, when executing the GO
command.
configuration including the hardware watchdog if it is enabled. Consequently, 35-pulse mode must be used if hardware
watchdog is enabled.
In addition, when ST7FLITEUS is used in 38-pulse mode, the internal 8 MHz RC is selected as clock source if option
CKSEL[1:0]=00h, otherwise, if CKSEL is not 00h, AWU RC is selected as clock source. External clock can not be selected
when using 38-pulse mode.
Limitation: In ST7FLITEUS when programming the LVD option from OFF to ON in 38-pulse mode and if the AVD is OFF,
a spurious reset is generated and ICC communication is lost. The workaround is either to use 35-pulse mode or to ensure
that the programming tool generates a reset after programming the Option Byte.
C000h. Take care to program Option byte 0, 1, 2 and 3 in the same routine. Then the following steps must be followed to
modify the option bytes:
-Read the 4 bytes in the device
-Modify as desired
-Write the 4 bytes in the device

protection has not been enabled. However it must be noted that only the program memory of these devices can be read but
not the option bytes.
