Product Description
The CM D G 65SC22 Versatile Interface Adapter (VIA) is a flexible I/O device for use with the CM D G 6 5 S C X X X series 8-bit
m icroprocessor family. The G 65SC22 includes functions for program m ed control of up to tw o peripheral devices (Ports
A and B). Two program controlled 8-bit bidirectional peripheral I/O ports allow direct interfacing between the m icro­
processor and selected peripheral units. Each port has input data latching capacity. Two program m able data direction
registers (A and B) allow selection of data direction (input or output) on a individual line basis. Also provided are two
program m able 16-bit interval timer/counters with latches. Tim er 1 may be operated in a one-shot interrupt mode with
interrupts on each count-to-zero, or in a free-run mode with a continuous series of evenly spaced interrupts. Tim er 2
functions as both an interval and pulse counter. Serial data transfers are provided by a serial-to-parallel/parallel-to-serial
shift register. Application versatility is further increased by various control registers, including — an interrupt flag
register, an interrupt enable register and two function control registers.
