We've received word that the 'F1 is being discontinued. The larger 68-pin PLCC package is going end-of-life in June (of THIS year, thanks for all the warning, Freescale) and the smaller 80-pin LQFP package is going end-of-life in June 2007 (that's a bit better warning). The key aspects we needed from the 'F1 was its ability for external addressing and the non-multiplexed address/data bus. W

Hi Guys, I am a student at okalhoma state university and I am trying to develop an ASIC version of the HC11 controller using verilog. This should be able to runn all the Hc1 instructions except for the ports and A/D. I am simulating the RAM and ROM through external buses. I want to tst my verilog code for functionality and timing. Is there a set of C/assembly test programs tha

Hi, I'm currently working on a project which requires me to use the serial communications interface on the M68Hc11 board to interface it with a Bluetooth module (Promi-SD 202). I need to test it by sending out a data using the module and verify if it is received by another set of Bluetooth device. After doing several references, I came up with a simple program to send 8 bit data to the

Hi, I am doing a senior design project at the University of Alabama at Birmingham. I am building a robot, and I am using the microStamp11 chip for some of the robot's simple operations. The microStamp11 chip is notorious for being the world's smallest HC11 chip. I am using the ImageCraft IC11 environment to compile my code and create Motorola .s

Hello, I need some help regarding the 68HC11E1 processor external memory interface. We are using the 614 KHz clock frequency and are using the processor custom chip which doesn't have internal program memory. We have tied the MODA and MODB pins to VCC thru pull-up resistors. The reset is thru external monitor chip.And we have interfaced flash as
