46.4.10 Interrupts

The following are the sources of QEI interrupts:

• Position counter overflow or underflow event
• Velocity counter overflow or underflow event
• Position counter initialization process complete
• Position counter greater than or equal compare interrupt
• Position counter less than or equal compare interrupt
• Index event interrupt
• Home event interrupt

The QEIx Status (QEIxSTAT) register contains the individual interrupt enable bits and the corresponding interrupt status bits for each interrupt source. A status bit indicates that an interrupt request has occurred. The module reduces all of the QEI interrupts to a single interrupt signal to the interrupt controller module.
