Type RW RW R RW RW RW RW RW
Default 0 0 0 0 0 0 0 0
Register: General-purpose event enable
Offset: 89h
Type: Read-only, Read/Write
Default: 00h
Table 4−11. General-Purpose Event Enable Register Description
BIT SIGNAL TYPE FUNCTION
7 ‡ PWR_EN RW Power change GPE enable. When this bit is set, GPE is signaled on PWR_STS events.
6 ‡ VPP12_EN RW 12-V V
PP
GPE enable. When this bit is set, GPE is signaled on VPP12_STS events.
5 RSVD R Reserved. This bit returns 0 when read. A write has no effect.
4 ‡ GP4_EN RW GPI4 GPE enable. When this bit is set, GPE is signaled on GP4_STS events.
3 ‡ GP3_EN RW GPI3 GPE enable. When this bit is set, GPE is signaled on GP3_STS events.
2 ‡ GP2_EN RW GPI2 GPE enable. When this bit is set, GPE is signaled on GP2_STS events.
1 ‡ GP1_EN RW GPI1 GPE enable. When this bit is set, GPE is signaled on GP1_STS events.
0 ‡ GP0_EN RW GPI0 GPE enable. When this bit is set, GPE is signaled on GP0_STS events.
‡
This bit is cleared only by the assertion of GRST
.
