QUICK START GUIDE MC56F81000-EVK
OPERATION NOTES
1. MC56F81000-EVK can be powered by either of the USB connectors (J12, J26) or the
adapter input (J7). Beware that only an adapter with 5 V output can be used.
2. When the board is powered up, a green LED D2 will illuminate, indicating 3.3 V is
on. If the board is powered by the USB connector (J12), an orange LED D4 will also
illuminate, indicating K26 is powered.
3. J12 is the onboard OpenSDA (realized by K26) connector that can be used to
debug/program 56F81768.
4. J26 is the virtual serial port connector, which can be used by ROM bootloader.
CP210x USB to UART bridge VCP drivers are needed.
5. J10 is the JTAG connector for MC56F81768. Remember to remove the four jumpers
on J13 when this JTAG is used. This is to avoid the impact of on-board OPenSDA
circuit.
6. J14 is the JTAG connector for the K26 firmware update.
7. Device boot from flash after reset by default, changing macro “ENTER_
BOOTLOADER” in Project_Settings> Startup_code>Cpu.c to enable ROM
bootloader. When “ENTER_BOOTLOADER” is set, Boot ROM code is executed
first out of reset. The ROM bootloader takes about 6 seconds to check the active
communication port (I
2
C, SCI) before the application code is executed.
8. The device runs in normal mode (50 MHz operation frequency) by default, setting
macro “STARTUP_FAST_MODE” in Project_Settings>Startup_code>Cpu.c will
configure the device to run in fast mode (100 MHz operation frequency).
9. Connect pin2 and pin3 of J11 to enable the external reset from SW1.
