6.9 Extention Port
To accommodate some user functions, the extention port on the EK-5744 contains
some 3.3V tolerant CPU pins and a 3.3V supply. All GPIOs are the direct unpro-
tected CPU ports, so care must be taken not to exceed the IO specifications of the
MPC5744P. The 3.3V rail is not able to deliver more than 250mA.
The extention port EXT is realized as an 18-pin header with 2.54mm pitch.
