Registers 0x60 and 0x61 set the base address
for the device. If more than one base address
is required, the second base address is set by
registers 0x62 and 0x63.
Unused registers will ignore writes and return
zero when read.
Note:
device is not within the Base I/O range as
shown in the Logical Device I/O map, then
read or write is not valid and is ignored.
0x70 is implemented for each logical device.
Refer to Interrupt Configuration Register
description. Only the keyboard controller uses
Interrupt Select register 0x72. Unused register
(0x72) will ignore writes and return zero when
read. Interrupts default to edge high (ISA
compatible).
Refer to Table 11.5
Note:
Interrupt Select register for logical device 0 is
0x06.
Reserved - not implemented. These register
locations ignore writes and return zero when
read.
Only 0x74 is implemented for FDC and Parallel
port. 0x75 is not implemented and ignores
writes and returns zero when read. Refer to
Table 11.6.
Note: The default value of the DMA Channel
Select register for logical device 0 (FDD) is
0x02 and for logical device 4 (UART) is 0x04.
Reserved - not implemented. These register
locations ignore writes and return zero when
read.
Reserved - not implemented. These register
locations ignore writes and return zero when
