10.5.3. Commands
The MC supports PC104 with memory and I/O instructions. For further
information on these commands, refer to the SERVOSTAR
®
MC Reference
Manual.
If you are using memory-mapped PC104 cards, you will need the memory
access commands, PEEK and POKE. The valid memory address range for
PEEK is 0xA0000 through 0xDFFFF. The valid memory address range for
POKE depends on the hardware version of the MC card.
For the ISA-Bus card, the valid memory address range for POKE is
0xA0000 to 0xCFFFF and 0xDA000 to 0xDFFFF.
For the PCI card, the valid memory address range for POKE is
0xA0000 to 0xC7FFF and 0xDB000 to 0xDFFFF.
PEEKB transfers byte-wide (8-bit) data from the PC104 memory
bus to a variable.
PEEKW transfers word-wide (16-bit) data from the PC104
memory bus to a variable.
POKEB transfers byte-wide (8-bit) data to the PC104 memory bus.
POKEW transfers word-wide (16-bit) data to the PC104 memory
bus.
If you are using I/O-mapped PC104 cards, you need INP and
OUT.
INPB transfers byte-wide (8-bit) data from the PC104 I/O bus to a
variable.
INPW transfers word-wide (16-bit) data from the PC104 I/O bus to
a variable.
OUTB transfers byte-wide (8-bit) data to the PC104 I/O bus.
OUTW transfers word-wide (16-bit) data to the PC104 I/O bus.
