10.1.32 OCMAP—Over-Current Mapping Register
Address Offset: 74-77h Attribute: R/W
Default Value: C0300C03h Size: 32 bits
Function Level Reset: No Power well: Suspend
16 SMI on HCReset — R/WC. Software clears this bit by writing a 1 it.
0 = HCRESET did Not transitioned to 1.
1 = HCRESET transitioned to 1.
15:6 SMI on PortOwner Enable — R/W.
0 = Disable.
1 = Enable. When any of these bits are 1 and the corresponding SMI on PortOwner bits are
1, then the host controller will issue an SMI. Unused ports should have their
corresponding bits cleared.
5 SMI on PMSCR Enable — R/W.
0 = Disable.
1 = Enable. When this bit is 1 and SMI on PMSCR is 1, then the host controller will issue an
SMI.
4 SMI on Async Enable — R/W.
0 = Disable.
1 = Enable. When this bit is 1 and SMI on Async is 1, then the host controller will issue an
SMI
3 SMI on Periodic Enable — R/W.
0 = Disable.
1 = Enable. When this bit is 1 and SMI on Periodic is 1, then the host controller will issue an
SMI.
2 SMI on CF Enable — R/W.
0 = Disable.
1 = Enable. When this bit is 1 and SMI on CF is 1, then the host controller will issue an SMI.
1 SMI on HCHalted Enable — R/W.
0 = Disable.
1 = Enable. When this bit is a 1 and SMI on HCHalted is 1, then the host controller will issue
an SMI.
0 SMI on HCReset Enable — R/W.
0 = Disable.
1 = Enable. When this bit is a 1 and SMI on HCReset is 1, then host controller will issue an
SMI.
Bit Description
Bit Description
31:24 OC3 Mapping Each bit position maps OC3 (EHCI 1) to a set of ports as follows:
EHCI 1: Map OC3
It is software responsibility to ensure that a given port‘s bit map is set only for one OC pin.
23:16 OC2 Mapping Each bit position maps OC2 (EHCI 1) to a set of ports as follows:
EHCI 1: Map OC2
It is software responsibility to ensure that a given port‘s bit map is set only for one OC pin.
