Multiplexing Pins Between SDRAM and
FLEXBUS on K65/K66
1. Introduction
This application note introduces the key features on
K65/K66, where pins can be multiplexed between the
SDRAM and FLEXBUS port. This helps save many
pins in the application and is useful in applications that
require many function pins.
