That depends.  The MSSP in slave mode can do clock stretch on a read, so
there is a means of flow control in that direction.  Unfortunately Microchip
didn't implement clock stretch for writes, although there are other ways to
deal with this.  Data coming into the slave IIC port is not that much
different than data coming into the UART.  Eventually you still have to
handle it at the speed it decides to come at.
