Introduction FLASH PSD813F devices are members of a family of flash-based peripherals for use with embedded microcontrollers (MCUs). These programmable system devices (PSDs) consist of memory, logic, and I/O. When coupled with a low-cost, ROM-less 68HC11 MCU, the PSD ...

A Common Solution For ISP, some 68HC11 designers will use the boot-loader feature of the 68HC11 UART to download executable code into SRAM (either the small on-board 68HC11 SRAM or an external SRAM chip) then the 68HC11 jumps to that ...

MCU in silicon. No extra design effort on your part is needed. This MCU access feature is great for loadable shift registers, counters, mailboxes, state machines, etc. There are 27 I/O pins that ...

Physical Connections Connect your 68HC11 to the PSD as shown. The same connections can be used for all five members of the PSD813F family (PSD813F1 though PSD813F5). Notice that the 16 general purpose I/O lines that were lost on ...

To make this division of the memory map possible (i.e. common upper half, paged lower half), the 68HC11 initialization firmware must move the internal 68HC11 SRAM and registers from their default location of 0000h, to the new location of 8000h, ...

Design Flow Window The design flow window shows all of the major steps of the design process. Clicking on a box within the design flow window invokes the associated process. You should see this: 2.3.3 Device Configuration Click on ...

Edit the template. The default 68HC11 template that you see on the screen has numerous elements inside to illustrate many features of the FLASH PSD813F. To simplify things, edit this template file that you see to look like the ...

For this simple example, you can ignore the warning and click ‘OK’ because we are only placing 68HC11 code into EEPROM segments EES0 and EES1, which are not paged. But here is an explanation of this warning will ...

Now slide the scroll bar down until see the following: Type in the name of the file from your 68HC11 linker that contains the firmware that will boot up your system. Use your own file name. For this example we’ll ...

Conclusion These examples are just two of an endless number of ways to configure the FLASH PSD for your system. Concurrent memories with a built-in programmable decoder at the segment level offer excellent flexibility. Also, as you have seen ...
