7.7.12 INT_CFG - interrupt configuration register (address 45h)

The interrupt configuration register contains configuration information for the interrupt output. This register can

be written during initialization but is locked once the ENDINIT bit is set (see Section 7.7.4 "DEVLOCK_WR -

lock register writes register (address 10h)"). The register is included in the read/write array error detection.
