4.2. Pin connections in parallel programming mode<br />

Resetting after setting the MD[2:0] pins to [111] will halt CPU functioning. At this time, the Flash memory’s<br />

interface circuit enables direct control of the Flash memory unit from external pins by directly linking some of<br />

the signals to General Purpose Ports. Please see table below for signal mapping.<br />

In this mode, the Flash memory appears to the external pins as a stand-alone unit. This mode is generally set<br />

when writing/erasing using the parallel Flash programmer. In this mode, all operations of the 8.5 Mbits Flash<br />

memory’s Auto Algorithms are available.<br />
