Serial Interface Module Interrupt
The Serial Interface Module Interrupt, also known as the SIM interrupt, is contained within the
Multi-function Interrupt. A SIM Interrupt request will take place when the SIM Interrupt request
ag, SIMF, is set, which occurs when a byte of data has been received or transmitted by the SIM
interface, an I
2
C slave address match or I
2
C bus time-out occurrence. To allow the program to
branch to its respective interrupt vector address, the global interrupt enable bit, EMI, the Serial
Interface Interrupt enable bit, SIME, and Muti-function interrupt enable bit must rst be set. When
the interrupt is enabled, the stack is not full and any of the above described situations occurs, a
subroutine call to the respective Multi-function Interrupt vector, will take place. When the Serial
Interface Interrupt is serviced, the EMI bit will be automatically cleared to disable other interrupts,
however only the Multi-function interrupt request ag will be also automatically cleared. As the
SIMF ag will not be automatically cleared, it has to be cleared by the application program.
