State of I2C question
Posted: Thu Nov 02, 2006 1:06 am
I have a question about the state of the I2C pins during normal operation. I don't have the eval board (yet) and I don't see schematics for it on the Spin site, but what I'm designing is functionally similar.
I presume that any change of the S0-S2 pins when T0 is high causes the FV-1 to start downloading the selected program into internal RAM and after that the E2PROM is sitting idle. Can I reprogram the E2PROM without interference while it is still connected to the FV-1 when the FV-1 is running from internal memory?
Also, the datasheet is very clear that T1 must be grounded for normal operation, but can anybody comment about the actual function of the T1 input?
Thanks for a very cool chip!
