In addition to the 4MHz crystal, there is also a 25MHz oscillator (Y3) which feeds the Ethernet chip (U20).

  • Page 19: Exception Sources

    Programming two interrupt sources with the same level and priority can result in undefined operation. The MPC564EVB hardware uses IRQ[0]/SGPIOC[0] to support the ABORT (Non Maskable Interrupt) function using the ABORT switch (SWITCH1 when BRK_EN jumper is inserted). This switch is used to force a non-maskable interrupt if the user's program execution should be aborted without issuing a RESET.

  • Page 84 To display the current baud rate of the board, the command is: show baud Here is an example of the output from a show command: dBUG> show base: 16 baud: 19200 server: 192.0.0.1 client: 192.0.0.2 gateway: 0.0.0.0 netmask: 255.255.255.0 filename: test.srec filetype: S-Record mac: 00:CF:52:49:C3:01 speed: 56000000 3-34 MPC564EVB User’s Manual...
  • Page 85 Commands STEP Step Over Usage: STEP The STEP command can be used to “step over” a subroutine call, rather than tracing every instruction in the subroutine. The ST command sets a temporary software breakpoint one instruction beyond the current program counter and then executes the target code. This command only works when executing code in SRAM.

  • Page 87 Commands TRACE Trace Into Usage: TRACE <num> The TRACE command allows single-instruction execution. If num is provided, then num instructions are executed before control is handed back to dBUG. The value for num is a decimal number. The TRACE command sets bits in the processors’ supervisor registers to achieve single-instruction execution, and the target code executed.

    System Call Functions 3.5 System Call Functions An additional utility within the dBUG firmware is a function called the System Call handler. This function can be called by the user program to utilize various routines within dBUG, to perform a special task, and to return control to dBUG.
