I2C "READ" Setup/Hold Requirement

Hello

For the I2C read, the step by step, the algorithm is:

1). write slave address+write bit
2). write register address
3). write slave addres+read bit
4). read

After the end of step 2, and before step 3, you need to set the STA to
indicate the real read. Note that STA is indicated by transition of
HIGH to LOW on the SDA while SCL remains HIGH. I am wondering if there
is minimum wait time between step 2 and beginning of step 3?

Note that my design uses OpenCores' I2C (if it matters). Thanks.

Happy Turkey Day,
