Note:

1.

2.

An example circuit design can be found on the Module Development Board schematic. An external data bus buffer is recommended for

any designs that use data bus signals D16 - D31.

3.

J2-31 represents TIN0 and PB4/UART0 external baud rate clock. These two signals are tied together on the module PCB.

4.

The ColdFire 5272 processor supports USB device mode only. A 48Mhz oscillator must be installed in locaton U8 of the Mod5272.
