2-10 Freescale Semiconductor
Preliminary
2.5.3 CLKMODE
The 56F8367EVM provides a clock boot mode jumper, JG6. This jumper is used to select the
type of clock source being provided to the processor as it exits reset. The user can select between
the use of a crystal or an oscillator as the clock source for the processor. Refer to the
56F8300
Peripheral User Manual and the 56F8367 Technical Data Sheet for a complete description of
the chip’s operating modes. Table 2-5 shows the two CLKMODE operation modes available on
the 56F8367.
Table 2-5. EMI Operating Mode Selection
Operating Mode JG6 Comment
Crystal 1 - 2 Enables the external clock drive logic so an external
crystal can be used as the input clock source. (GND)
Oscillator No Jumper Disables the external clock drive logic. Use oscillator
input on XTAL and Ground on EXTAL. (3.3V)
2.6 Debug LEDs
Six on-board Light Emitting Diodes, (LEDs), are provided to allow real-time debugging for user
programs. These LEDs will allow the programmer to monitor program execution without having
to stop the program during debugging; refer to
Figure 2-5 . Table 2-6 describes the control of
each LED.
