UART2 Clear to Send Input. Has no function in IrDA
and CIR modes.
(1) I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground, A = Analog signal.
(2) PULL: A / B, where:
A is the state of the internal pull resistor during POR reset
B is the state of the internal pull resistor after POR and Warm reset are de-asserted and during Warm reset
IPD = Internal Pulldown Enabled, IPU = Internal Pullup Enabled, DIS = Internal Pull Disabled
DRIVE: A / B, where;
A is the driving state of the pin during POR reset
B is the driving state of the pin after POR and Warm reset are de-asserted and during Warm reset
H = Driving High, L = Driving Low, Z = 3-State
For more detailed information on pullup/pulldown resistors and situations where external pullup/pulldown resistors are required, see
Section 4.2.1, Pullup/Pulldown Resistors.
(3) Specifies the operating I/O supply voltage for each signal.
