1 Port connections may be inputs or outputs after power up depending on the model and boot mode chosen.
2 All port connections always power up as inputs for some period of time and require resistive termination to a safe condition if used as outputs in the system.
3 A total of 32 interrupts at once are available from ports C through J, configurable in byte-wide blocks.
4 GPW functionality available when MXVR is not present or unused.
