Interrupt 0xA2 service 0x80: PFE: Enable Data Bus
Parameters
AH
AL
DX
Initialize data bus I/O mask and ALE usage.
Must be 0x80.
0: Disable ALE, 1: Enable ALE
Mask
Return Value
none
Comments
Bit 0 = 0: Data bus bit 0 is input, 1: is output
Bit 1 = 0: Data bus bit 1 is input, 1: is output
:
:
Bit 7 = 0: Data bus bit 7 is input, 1: is output
Bit 8..15 not used (for future extensions)
The I/O mask defines which data bits on the bus are inputs and which are outputs. The DX mask bit for
bi-directional data bus lines (read/write) should be set to '1'.
