Chapter 54 Flash Memory
6.Flash Access Mode Switching
6.1 Flash Memory Mode
Resetting after setting the MD2, MD1 and MD0 pins to “1”, “1” and “1” will halt the MCU functions. At this time,
the Flash memory's interface circuit functions are emabled for direct control of the Flash memory unit from
external pins, by directly linking some of the signals to the Flash memory unit's control signal. 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 Flash memory's Auto
Algorithms are available.
For correspondence between the MCU pins and Flash memory’s interface circuit in the flash parallel
programming mode please check the related datasheets of each product.
