A.2 Bus Loading
You must pay careful attention to bus loading when designing an interface to the
RCM3365/RCM3375. This section provides bus loading information for external devices.
Table A-2 lists the capacitance for the various RCM3365/RCM3375 I/O ports.
Table A-3 lists the external capacitive bus loading for the various RCM3365/RCM3375
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.
