C M L 1 2 S D P 2 5 6 0 1 / 3 0 / 0 4 At minimum, you should install the AxIDE program. This provides the flash programming utility and communication with the board via the COM port and the supplied serial cable. This program includes a simple terminal for interfacing with other programs running on the CML12Sxxx and information from your own programs that send output to the serial port. -

CD and if you installed AxIDE, under that programs \EXAMPLE directory. You must use the example for the MCU type installed on the CML12Sxxx board. For example use the CML12S-DP256 example on the DP256 version board. You can assemble source code by using the AxIDE "BUILD" button or command line tools under a DOS prompt by typing: AS12 HELLO.ASM –L HELLO... -

Page 9: Mon12 Operation
Start for application starting from Reset. MON12 operation notes: 1. CML12S-DP256 monitor application configures target HCS12 for 8MHz E clock, lower flash block (page $3E) disabled from memory map, and external access clock stretch set to 3 cycles. User can increase clock speed in application by modifying PLL control and setting new baud rate for serial port. -

C M L 1 2 S D P 2 5 6 0 1 / 3 0 / 0 4 B) Set Stack, Initialize memory map and SCI0 port and send prompt. C) Receive first character from Console port and execute monitor if ASCII text / command, else start utility mode for programming services. -
Page 11: Mon12 And Noice Memory Map
See the NOICE documentation for details. The CML12S-DP256 provides the NOICE debug monitor kernel as a subset of the MON12 monitor in reserved flash memory. User may apply the NOICE development system by setting the MON12 Autostart for the $F800 vector, reset the board and launch the NOICE host software on the PC. -
Page 12: Bdm Operation
2 hardware breakpoints. Operation Notes for BDM use: CML12S-DP256 MODC Option Jumper should be installed if a BDM is connected to the BDM Port. Default Mode is single-chip so the MODC option installed will force Special Single-chip Mode on Reset. -

MODE The MODE option jumper is not installed on the CML12S-DP256 board and is hard connected by circuit copper trace for Single-chip Mode operation of the CPU. Both the MODA and MODB signals are terminated by this option. Due to the restriction that the HCS12 internal flash memory is the only nonvolatile program memory provided on the board, single Chip Mode is default. -

C M L 1 2 S D P 2 5 6 0 1 / 3 0 / 0 4 The 1,4,6,7,8, and 9 pins provide RS232 flow control and status. These are connected on the on the bottom of the development board to provide NULL status to the host. User may isolate pins and provide flow control or status connection to the host by applying HCS12 I/O signals and RS232 level conversion. -
