As the I2DAT has no buffer there is pretty less time to save or load I2DAT after an IRQ. As a slave receiver I asume I have about 10 us before I2DATA is overwritten. But what as a slave transmitter? 5us? You have all time of the world to do anything. The slave hardware hold SCL = low as long as you need for handling the I2C-event. But mostly the master implement a time out of about 1..10ms until it waits for SCL = high again. And if this time expired the master assume, that the transfer was failed. Peter |
