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 16.5 Mbits Flash
memory’s Auto Algorithms are available.
