Hello 

This is my ARM Based work : 

1. Act as an I2C PROM via the I2C channel.
2. Receive configuration orders from the I2C channel.
3. Read HW configuration via IO pins.
4. Configure an external component using a multiplexed 8 bit 
data/address bus,
should be implemented by GPIO.
5. Drive several HW pins according to configuration (including LEDS).
6. A frequency divider (externally sourced).

Open questions :
1. Our clock source is a 25MHZ clock signal. it will not be available
immediately with power up but as an output from another component. is 
this o.k.

I need your advice .

Thanks
