A.2 Bus Loading
Pay careful attention to bus loading when designing an interface to the RCM3600. This
section provides bus loading information for external devices.
Table A-2 lists the capacitance for the various RCM3600 I/O ports.
Table A-3 lists the external capacitive bus loading for the various RCM3600 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.
