XTALIN
14.7456 MHz Crystal Oscillator pins. For an external
clock source, XTALIN can be used while XTALOUT is
left unconnected. XTALIN voltage is 1.8 V nominal.

WIDTH0
Boot Width Pins. Used with the MEDCHG and INT-
BOOT bits for internal Boot ROM. On power up, the
values on these pins are latched to determine the
width and type of Boot device. Boot width can be 8-,
16-, or 32-bit. The pins must be pulled HIGH with a 33
k
resistor.
