P&E Microcomputer Systems has expanded its line of UNIT Library Interface Routines by adding a new version that supports Freescale's RS08 microcontroller family. P&E's UNIT Libraries allow the user to create custom Windows applications that can fully control an RS08 processor using either P&E's Cyclone PRO (Rev. C) or USB-ML-12 (Rev. C)  interfaces. It also supports P&E's DEMO9RS08LA8, DEMO9RS08LE4, and DEMO9RS08KB12 development boards, available through Freescale.

The UNIT libraries are frequently used to build custom production line testers. The libraries allow applications to peek and poke memory, peripherals, and other resources of the processor by using P&E interfaces to access the debug port. With these abilities, the application can perform tests of the target hardware, calculate target calibration data, or simply control the target using debug mode. 

More information about P&E's UNIT Interface Library Routines for the RS08 can be found at P&E's website.


PEmicro's flash programming software PROG12Z now supports the Freescale MC9S12XE family of microcontrollers. 

The MC9S12XE family of microcontrollers comes with unique flash memory called D-Flash that can be allocated for Emulated EEPROM (EEE)  which mimics the small sector size and endurance of real eeprom. Before you can program the D-Flash or EEE, the D-Flash must be configured with the "Full Partition" command PROG12Z. This article discusses how to program the D-Flash of MC9S12XE100 using PROG12Z. The P-Flash does not support the allocation of EEE and therefore does not require partitioning.


The size of the D-Flash on the MC9S12XE can be up to 32KB or 128 sectors of 256 bytes each. You can allocate up to 4KB or 16 pages of 256 bytes each  to be used for EEE. Please see Freescale application note AN3490 for a more detailed overview of the EEE implementation. There are two  parameters that control how the software configures the memory: DFPART and ERPART.

DFPART = Number of D-Flash sectors reserved as User D-flash (128 total)

ERPART = Number of pages reserved for EEE (16 total)

The two parameters are required to meet two size conditions to be valid:

1. (128-DFPART) / ERPART >= 8

2. (128-DFPART) >= 12 if ERPART==1

The following table shows how the flash memory can be allocated towards D-Flash and EEE. The arrows indicate that any number in that range is a valid amount of sectors for D-Flash. DFPART and ERPART are in hexadecimal notation.


Open Prog12z and connect to the target board. After entering background mode, the software will prompt you for an algorithm. There are two seperate algorithms for D-Flash and EEE. The D-Flash algorithm is "Freescale_9S12XEP100_1x16xmax16k_max32k_Linear_User_Dflash.12P". The EEE algorithm is "Freescale_9S12XEP100_1x16xmax2k_max4K_EEPROM_linear_1k_page.12P".

Lets choose the algorithm for D-Flash. After selecting your S19 file and before programming, execute the Full Partition (FP) command. The software will prompt you to enter a value in hexadecimal that is the combination of DFPART and ERPART parameters. 


"8000" - Enables 128 sectors (32 KB) of D-Flash and 0 pages of EEE 

"200C" - Enables 32 sectors (8 KB) of D-Flash and 12 pages (3 KB) of EEE

"100C" - Enables 16 sectors (4 KB) of D-Flash and 12 pages (3 KB) of EEE

"0010" - Enables 0 sectors of D-Flash and 16 pages (4 KB) of EEE 

When you want to program the EEE, you should choose the algorithm for EEE. You do not need to run the Full Partition command again unless you want to change the memory configuration. Note that setting up the memory configuration using the FP command will erase all the contents of both D-Flash and EEE.  If you get the error message "Started. Error during .12P specified function.", you have entered an invalid value.


The D-Flash begins at 0x100000. If all your memory is allocated towards D-Flash only, execute the Upload Module (UM) command to dump the memory to a S19 file. UM reads the entire flash regardless of how it was partitioned. If there is D-Flash and EEE, execute the Upload Range (UR) command instead. For example, if there is 8 KB of D-Flash, then upload the range 0x100000 to 0x101FFF.
