Terminal Settings
The utility software provided uses the serial port connected to your PC running a terminal program as described under "Getting
Started". While you can use almost any commercial or free serial communications terminal interface, it is important that you
configure it to work properly with this board. The following settings are important:
1. BPS: 19.2K baud, Data Bits 8, Parity none, Stop Bits 1
2. Flow Control should be set to SOFTWARE or XON/ XOFF method to support this monitor.
3. Emulation should be ANSI
4. When uploading files to the board, be sure to send in Text mode.
5. When programming FLASH type memory, you must use the XON / XOFF flow control.
The free terminal program that works well with this board called “AXIDE” is provided on the support CD. It is also available for
download from the manufacturers web site at www.axman.com.
Software Development
The provided monitor software initializes the clock to run this board at 56 MHz and configures the SCI1 baud rate to 19.2K baud at
this clock frequency. The default clock frequency is 20Mhz from Hard Reset condition. User can set the clock frequency by
changing the PLL Registers of the MPC562 in the initialization software. Software operated under the monitor’s control should not
change the clock setting or baud rate unless necessary. Changing the baud rate or clock setting will effect the monitor’s
communication and may require application of Reset to recover the monitor.
The MPC562BC is best applied with operating evaluation software that will exercise different features of the MPC562 device. The
dBUG Monitor installed will provide supervision of loading and executing software examples.
Applying a BDM Cable
The MPC562BC board is not recommended for BDM tool assisted software development and debugging. The BDM port is
provided primarily to initialize and test the board at the factory. The user may apply BDM based tools to the board without warranty
or support. The following notes apply to BDM operation on the MPC562BC board:
1) Power Sequencing: The BDM cable should only be installed while the MPC562BC board is not powered. If the MPC562BC
board is powered off, the BDM cable should be removed and reapplied prior to applying power to the MPC562BC board again.
2) JP3 = 3.3V BDM: Some BDM cables may prevent proper power up by the Power oak power supply device when the JP3 BDM
voltage selection is set to the 3.3V position. The trouble symptom in this case is that power is applied to the MPC562BC board
but the voltage indicators will not light and no voltages are available. The cure to this problem is to remove the JP3 = 3.3V
BDM option jumper prior to applying power to the MPC562BC board with the BDM installed. After power-up, install the JP3 =
3.3V BDM option jumper and press the PORESET button once. This problem should not occur in the JP3 = 2.6V BDM option
setting if correct sequencing of connections and power are performed.
3) User Memory space: The BDM environment user memory space is limited to the MPC562 internal SRAM memory from
0x3F8000 > 0x3FFFFF. The BDM will not be able to load the external flash memory unless it has utilities to perform a parallel
2 x 16 bit wide flash memory programming operation. BDM code execution control may not operate in the external memory
space unless hardware breakpoint features are provided.
