SBAS386C – MAY 2006 – REVISED JULY 2007

Individual interrupts can be masked by clearing the corresponding interrupt enable bit in the configuration

registers to prevent SMBALERT interrupts. Note that masking an interrupt source only prevents the SMBALERT

pin output from being asserted; the appropriate status bit gets set as normal.
