DESCRIPTION
X1/CLK is the input for either a
24MHz clock crystal or 24MHz
crystal oscillator source (see
section CLOCK GENERATOR on
page 12)
X2 is the 24MHz crystal driver and
should be left unconnected if an
external clock source is used.
The Host Interface Select bits
determine the host interface type.
These bits are static controls and
must remain stable during device
operation (see section
MULTIHOST CPU INTERFACE
on page 13).
The general purpose I/O pins
provide a simple programmable
I/O interface. The state of a GPIO
pin can be forced to the value
contained in the GPIO data
register or this register can reflect
the logical state of the GPIO pin
depending on values programmed
in GPIO direction and enable
registers (see section GENERAL
PURPOSE I/O on page 32).
