Reset Output to external devices. This pin carries the
same state as the internal SoC reset signal.
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.
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 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
kΩ 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 64 kB address-
es are mapped to the internal Boot ROM.
