11. Introduction
MC8041A is a high-speed 4-axis PC-Based motion control card for stepper or pulse-type servo motor drivers.
Its features are:
. 4-axis independent position / speed control for stepper / pulse-type servo motor drivers
. Linear interpolation for any 2 or 3 axes
. Circular interpolation for any 2 axes
. Bit pattern interpolation for any 2 or 3 axes
MC8041A, equipped with our 4-axis motion control IC MCX314, can be directly connect to the ISA bus
expansion slot on PCs and their compatible machines.
The following is the functional blocks of MC8401A including MCX314, ISA BUS interface and each I/O
interface. Please refer MCX314 manual for the functions in details.

2. I/O Address Setting and Read / Write Register
I/O Address Setting
The I/O port address of MCX314 includes the higher 12 bits, SA15~SA4, of ISA bus I/O address SA15~SA0.
This address is set by SW1 and SW2 slide dip switches. The lower 3 bits, SA3~SA1, are used for IC internal
read / write register codes.
The slide dip switches SW1 and SW2 are with ON and OFF level for SA15 ~ SA4. Switch “ON” to set a
binary value 0; switch “OFF” to set a binary value 1 (see the graph below).
