General Description

The R65NC22 Versatile Interface Adapter (VIA) is a very flexible I/O control device.

In addition, this device contains a pair of very powerful 16-bit interval timers, a serial-to-parallel/parallelto serial shift register and input data latching on the peripheral ports.

Expanded handshaking capability allows control of bidirectional data transfers between VIA's in multiple processor systems.
