PIC16F84A I2C slave mode??

[Duncan]

Dear all:
I want to use PIC16F84A for I2C slave mode ,but I don't know
how to write.
Is there any sample code that I can refer to?
Thank you very much!!

Basically, you won't.
You will have to go completely 'DIY', and probably write a tight handler, using the interrupt input, controlled by the incoming I2C clock, to get the sort of response required.
The CCS software I2C, does not support slave operation, except on chips that have I2C hardware. It'd be much easier to use a latter chip, that has I2C hardware built in...

Sorry.
