Software Event Status. This bit indicates a host software event. It may operate in two modes depending on
HSECM bit in MSWCTL1 register.
When HSECM is cleared, this bit is set when bit 6 of WK_STS0 changes from 0 to 1.
When HSECM is set, this bit is set on a write of 1 to WK_STS0 bit 1. This bit is cleared by writing 1 to it.
0: Event not active (default)
1: Event active
Module IRQ Event Status. This sticky bit shows the status of the module IRQ event detection.
