General Purpose Event 1 Status [63:32] (GPE1_STS_63_32) – Offset 14
Note: This register is symmetrical to the General Purpose Event 0 Enable [127:96] Register. Unless indicated otherwise below, if the corresponding _EN bit is set, then when the STS bit get set, the processor will generate a Wake Event. Once back in an S0 state (or if already in an S0 state when the event occurs), the processor will also generate an SCI if the SCIEN bit is set, or an SMI# if the SCIEN bit is not set and GBL_SMI_EN is set.
Note that GPE0_STS bits 95:0 are claimed by the GPIO register block.
