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 4 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 4 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 power supply for the analog blocks of the buck regulator.
No internal connection.
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.
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.
