RabbitCore RCM3000

A.2  Bus Loading

You must pay careful attention to bus loading when designing an interface to the 
RCM3000. This section provides bus loading information for external devices.

Table A-2 lists the capacitance for the various RCM3000 I/O ports.

Table A-3 lists the external capacitive bus loading for the various RCM3000 output ports. 
Be sure to add the loads for the devices you are using in your custom system and verify 
that they do not exceed the values in Table A-3.
