PRODUCTION DATA
The LOCK_N pin can be configured to indicate an INT_N (interrupt) event. When configured as an INT_N output, the pin asserts low when an interrupt occurs, according to the programmed interrupt masks. Seven separate masks can be programmed through register control as interrupt sources:
INT_N is a sticky bit, meaning that it will flag after an interrupt occurs and will not clear until read-back. Once the Interrupt Status Register is read, the INT_N pin will assert high again. For more information about how to configure the LOCK_N pin for INT_N functionality, refer to the LMH1297 Programming Guide.
