NOTES:

1. CSI is a power-down signal. When high, the PAD is in stand-by mode and all its outputs

become non-active. See Tables 7A and 7B.

2. RESET deselects all PAD output signals. See Tables 8A and 8B.

3. A18, A17, and A16 are internally multiplexed with CS10, CS9, and CS8, respectively.

Either A18 or CS10, A17 or CS9, and A16 or CS8 can be routed to the external pins of

Port C. Port C can be configured as either input or output.
