I have to implement 400 KHz I2C on a Spartan 3E , and am considering using the PICOBLAZE controller for the purpose.However, I wanted to ask if there's anything equivalent to the tri state buffer in the PICOBLAZE instruction set.I need something to allow the reception of the acknowledge signal from the slave, which would normally require an I/O (Bi-directional) pin.
