Revision A1
10.7 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)
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.
10.8
Logical Device 7 (GP I/O Port I)
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 GP1 I/O base address [0x100:0xFFF] on 1 byte boundary.
CR62, CR 63 (Default 0x00, 0x00)
These two registers select GP14 alternate function Primary I/O base address [0x100:0xFFx] on
1~8 byte boundary, they are available as you set GP14 to be an alternate function (General
Purpose Address Decode).
CR64, CR 65 (Default 0x00, 0x00)
These two registers select GP15 alternate function Primary I/O base address [0x100:0xFFx] on
1~8
byte boundary, they are available as you set GP15 to be an alternate function (General
Purpose Address Decode).
CR70 (Default 0x00)
Bit 7 - 4: Reserved.
Bit 3 - 0: These bits select IRQ resource for GP10 as you set GP10 to be an alternate function
(Interrupt Steering).
CR72 (Default 0x00)
Bit 7 - 4: Reserved.
Bit 3 - 0: These bits select IRQ resource for GP11 as you set GP11 to be an alternate function
(Interrupt Steering).
