A.2 Bus Loading
You must pay careful attention to bus loading when designing an interface to the
RCM3700. This section provides bus loading information for external devices.
Table A-2 lists the capacitance for the various RCM3700 I/O ports.
Table A-3 lists the external capacitive bus loading for the various RCM3700 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.
