How to put I2C bus interface slave reception into wait state

Latest Updated:10/05/2016

Question:

How do I put the slave reception operation of the I2C bus interface into a wait state?

Answer:

If the RDRF bit is 1, a wait state is automatically entered (SCL becomes low level) at the fall of the eighth clock of SCL. To exit the wait state, read the ICDRR register.
