W83627HF/F
PRELIMINARY
CR70 (Default 0x01 if PNPCSV = 0 during POR, default 0x00 otherwise)
Bit 7 - 4: Reserved.
Bit [3:0]: These bits select IRQ resource for KINT (keyboard).
CR72 (Default 0x0C if PNPCSV = 0 during POR, default 0x00 otherwise)
Bit 7 - 4: Reserved.
Bit [3:0]: These bits select IRQ resource for MINT (PS2 Mouse)
CRF0 (Default 0x80)
Bit 7 - 6: KBC clock rate selection
= 00 Select 6MHz as KBC clock input.
= 01 Select 8MHz as KBC clock input.
= 10 Select 12Mhz as KBC clock input.
= 11 Select 16Mhz as KBC clock input.
(W83627HF/F-AW can support these 4 kinds of clock input, but W83627HF/F-PW only
support 12MHz clock input)
Bit 5 - 3: Reserved.
Bit 2: = 0 Port 92 disable.
= 1 Port 92 enable.
Bit 1: = 0 Gate20 software control.
= 1 Gate20 hardware speed up.
Bit 0: = 0 KBRST software control.
= 1 KBRST hardware speed up.
13.7 Logical Device 6 (CIR)
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 CIR I/O base address [0x100:0xFF8] on 8 byte boundary.
CR70 (Default 0x00)
Bit 7 - 4: Reserved.
Bit [3:0]: These bits select IRQ resource for CIR.
