Interrupt Generator Acknowledge Register, INT_ACK

The INT_ACK register acknowledges all level-sensitive interrupts that have been generated, and resets the INT_NUMBER register to zero.

It also resets the internal timer that is used for automatic interrupt generation. After acknowledging all interrupts using this register, the interrupt generator can be used again in another generation run.

The following table shows the bit assignments for the INT_ACK register.

Table 1. INT_ACK Register bit assignments
Bits Name Type Description
[0] ACK WO Write 1 to acknowledge all interrupts and reset the INT_NUMBER register to zero.

If the interrupt generator is not present, then this register is RAZ/WI.
