Data Sheet
These bits are set if an interrupt status occurs and an interrupt signal is activated if the
corresponding mask bit is set to “0”. If the mask bit is set to “1” no interrupt is generated,
however the interrupt status bit is set in ISTAS. RIC, SQC and SQW are cleared by
reading the corresponding source register S_STA, SQRR or writing SQXR,
respectively.
