W83637HF
CRF9 (Default 0x00)
Bit 7 - 3 : Reserved. Return zero when read.
Bit 2 _{: PME_EN: Select the power management events to be either an PME or SMI}
interrupt for the IRQ events. Note that: this bit is valid only when SMIPME_OE = 1.
=0
The power management events will generate an SMI event
Bit 1
Bit 0
=1
The power management events will generate an PME event.
: FSLEEP: This bit selects the fast expiry time of individual devices.
=0
1 second.
=1
8 milli-seconds
: SMIPME_OE: This is the SMI and PME output enable bit.
=0
Neither SMI nor PME will be generated. Only the IRQ status bit is set.
=1
An SMI or PME event will be generated.
CRFE, FF (Default 0x00)
Reserved for Winbond test.
8.5 Logical Device B (Hardware Monitor)
CR30 (Default 0x00)
Bit 7 - 1 : Reserved.
Bit 0 = 1 Activates the logical device.
= 0 Logical device is inactive.
CR60, CR 61 (Default 0x00, 0x00)
These two registers select Hardware Monitor base address [0x100:0xFFF] on 8-byte boundary.
CR70 (Default 0x00)
Bit 7 - 4 : Reserved.
Bit 3 - 0 : These bits select IRQ channel for Hardware Monitor.
8.6 Logical Device C (Smart Card interface)
CR30 (Default 0x00)
Bit 7 - 1 : Reserved.
Bit 0 : Logical device active bit.
= 0 Logical device is inactive.
= 1 Activates the logical device.
CR60, CR61 (Default 0x00, 0x00)
These two registers select Smart Card interface base address [0x100:0xFFF] on 8-byte boundary.
