In
The numbers in the circles show the status code held in the I2STAT register. At these
points, a service routine must be executed to continue or complete the serial transfer.
These service routines are not critical since the serial transfer is suspended until the serial
interrupt flag is cleared by software.
When a serial interrupt routine is entered, the status code in I2STAT is used to branch to
the appropriate service routine. For each status code, the required software action and
details of the following serial transfer are given in tables from
In the master transmitter mode, a number of data bytes are transmitted to a slave receiver
