HVQFN32 package die supply ground is connected to both V
ground for proper device operation. For enhanced thermal, electrical, and board level performance, the exposed pad needs to be
soldered to the board using a corresponding thermal pad on the board and for proper heat conduction through the board, thermal vias
need to be incorporated in the PCB in the thermal pad region.

Description
Request to Send (active LOW). A logic 0 on the RTS pin indicates the
transmitter has data ready and waiting to send. Writing a logic 1 in the modem
control register MCR[1] will set this pin to a logic 0, indicating data is available.
After a reset this pin will be set to a logic 1.
UART receive data. The RX signal will be a logic 1 during reset, idle (no
data), or when not receiving data. During the local loopback mode, the RX
input pin is disabled and TX data is connected to the UART RX input,
internally.
UART transmit data. The TX signal will be a logic 1 during reset, idle (no
data), or when the transmitter is disabled. During the local loopback mode, the
TX output pin is disabled and TX data is internally connected to the UART RX
input.
Power supply input.
Signal and power ground.
Crystal or external clock input. Functions as a crystal input or as an external
clock input. A crystal can be connected between this pin and XTAL2 to form an
internal oscillator circuit. Alternatively, an external clock can be connected to
this pin to provide custom data rates (see
rate
Output of the crystal oscillator or buffered clock. (See also XTAL1.)
Crystal oscillator output or buffered clock output. Should be left open if an
external clock is connected to XTAL1.
