Connect these two signals together to external 4.7uH inductor.
Connect this signal to other end of external 4.7uH inductor. 47uF capacitor to
GND is also required on this pin.
Indicates that 1.2V core has been powered up.
System reset (active low). In normal operation, this signal should be HIGH.
16-bit timer/counter external clock input.
Auto RS-485 mode enable (active low). This pin is sampled during power up,
following a hardware reset (RST#) or soft reset (register RESET). It can be
used to start up all 8 UARTs in the Auto RS-485 Half-Duplex Direction control
mode. The sampled logic state is transferred to FCTR bit-5 in the UART
channel.
Infrared mode enable (active low). This pin is sampled during power up, fol-
lowing a hardware reset (RST#) or soft-reset (register RESET). It can be
used to start up all 8 UARTs in the infrared mode. The sampled logic state is
transferred to MCR bit-6 in the UART.
Factory Test Modes. For normal operation, connect to GND.
3.3V I/O power supply.
3.3V analog PHY power supply. A ferrite bead is recommended on this pin.
3.3V power supply voltage for output stage of buck regulator.
3.3V power supply for the analog blocks of the buck regulator.
1.2V core power supply. A ferrite bead is recommended on these pins.
1.2V analog PHY power supply. A ferrite bead is recommended on this pin.
Power supply common, ground.
No internal connection.
