Pin connections in parallel programming mode
Resetting after setting the MD[2:0] pins to [111] will halt CPU functioning. At this time, the Flash memory’s interface circuit enables
direct control of the Flash memory unit from external pins by directly linking some of the signals to General Purpose Ports. Please
see table below for signal mapping.
In this mode, the Flash memory appears to the external pins as a stand-alone unit. This mode is generally set when writing/erasing
using the parallel Flash programmer. In this mode, all operations of the 8.5 Mbits Flash memory’s Auto Algorithms are available.
