Reset Output to external devices. This pin carries the
same state as the internal SoC reset signal.
14.7456 MHz Crystal Oscillator pins. To drive the device
from an external clock source, XTALIN can be used while
XTALOUT is left unconnected.
32.768 kHz Real Time Clock, Crystal Oscillator pins. To
drive the device from an external clock source, XTAL32IN
can be used while XTAL32OUT is left unconnected.
Programmable Clock (14.7456 MHz MAX.)
External Oscillator Enable Output
Boot Width Pins. Used with the MEDCHG and INTBOOT
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. These
pins have a weak internal pull-up resistor
Media Change bit; used at power on with INTBOOT and
WIDTHx pins to determine boot device.
When LOW, boot device is selected according to the
MEDCHG bit. When HIGH, the lower 64KB addresses
are mapped to the internal Boot ROM.
