Figure 4-1: Typical Implementation of VR4102 to SED1374 Interface
The NEC V
controller by providing the internal address decoding and control signals necessary. By
using the Generic # 2 interface, only one inverter is required to change the polarity of the
system reset signal to active low. A pull-up resistor is attached to WAIT# to speed up its
rise time when terminating a cycle.
The following diagram shows a typical implementation of the VR4102 to SED1374
interface.
