65 / 240 page  2.0 Device Architecture and Configuration (Continued) 65 www.national.com 2.14.2 Logical Devices 5 and 6 (Mouse and Keyboard) Configuration Tables 25 and 26 list the configuration registers which affect the Mouse and the Keyboard respectively. Only the last register (F0h) is described here. See Sections 2.2.3 and 2.2.4 for descriptions of the others. Table 25. Mouse Configuration Registers Table 26. Keyboard Configuration Registers Index Mouse Configuration Register or Action Type Reset 30h Activate. See also bit 0 of the SIOCF1. When the Mouse of the KBC is inactive, the IRQ selected by the Mouse Interrupt Number and Wake-Up on IRQ Enable register (index 70h) is not asserted. This register has no effect on host KBC commands handling the PS/2 Mouse. R/W 00h 70h Mouse Interrupt Number and Wake-Up on IRQ Enable register R/W 0Ch 71h Mouse Interrupt Type. Bits 1,0 are read/write; other bits are read only. R/W 02h 74h Report no DMA assignment RO 04h 75h Report no DMA assignment RO 04h Index Keyboard Configuration Register or Action Type Reset 30h Activate. See also bit 0 of the SIOCF1. R/W 01h 60h Base Address MSB register. Bits 7-3 (for A15-11) are read only, 00000b. R/W 00h 61h Base Address LSB register. Bits 2-0 are read only 000b. R/W 60h 62h Command Base Address MSB register. Bits 7-3 (for A15-11) are read only, 00000b. R/W 00h 63h Command Base Address LSB. Bits 2-0 are read only 100b. R/W 64h 70h KBD Interrupt Number and Wake-Up on IRQ Enable register R/W 01h 71h KBD Interrupt Type. Bits 1,0 are read/write; others are read only. R/W 02h 74h Report no DMA assignment RO 04h 75h Report no DMA assignment RO 04h F0h KBC Configuration register R/W 40h |
