Table 23: SYS_EVENT_0 (0x0004) Bit Symbol Description
SG caused event. Writing 1 action clear this bit into 0 if event source has [2] E_SG been released. TEMP_CRIT caused event. Writing 1 action clear this bit into 0 if event [1] E_TEMP_CRIT source has been released. TEMP_WARN caused event. Writing 1 action clear this bit into 0 if event [0] E_TEMP_WARN source has been released.
Table 24: SYS_EVENT_1 (0x0005) Bit Symbol Description
PG2 caused event. Writing 1 action clear this bit into 0 if event source has [7] E_PG2 been released. OV2 caused event. Writing 1 action clear this bit into 0 if event source has [6] E_OV2 been released. UV2 caused event. Writing 1 action clear this bit into 0 if event source has [5] E_UV2 been released. OC2 caused event. Writing 1 action clear this bit into 0 if event source has [4] E_OC2 been released.
