Laboratory Reference Manual by Dustin Spicuzza

The Lab Reference Manual includes instructions to Flash EEPROM programming.       

A previous Flash Programming Guide by Ramakrishna Gottipati is here.    Updated  D-BUG12 .s19 file

Please note that when you develop code for uCOS-II tasks you are to refrain from programming the PLL
because NOICE may crash.

Information regarding to the length of a machine/memory cycle for a 9S12DP256/DP512 chip with a 16MHz crystal:

                 - if you download your code directly from ICC12 to the board and run it under DBUG-12 (as you
                   likely do outside of the Microcomputer Lab) the measured period time of the ECLK signal is approx. 42ns
                   (i.e., the Bus Speed is 24MHz). It is due to the fact that the DBUG-12 Monitor sets up the PLL such that
                   the default 8MHz clock speed will be multiplied by 3.

                 - However, in the lab you download and run your programs through the NOICE12 sw and the BDM12SX
                   BDM Module. The measured period time of the ECLK signal is approx. 126ns (i.e., the Bus Speed is 8MHz)
                   because the NOICE12 program leaves the PLL alone. You have to program the PLL from your code if
                   you want your board to run at 24MHz in the lab. However, when you develop a task for the uCOS-II RT Kernel
                   stick with the 8MHz Bus Speed because it is the default value for the Kernel. If you need to step up the clock rate
                   then you also need to edit the Kernel source code accordingly.
