Request to Send. Indicates that a Host Controller is ready to
receive data from the MCP2140A. This signal is locally
emulated and not related to the CTS/RTS bit of the IrDA
Primary device.
1 = Host Controller not ready to receive data
0 = Host Controller ready to receive data
Positive supply for logic and I/O pins.
Oscillator crystal output.
Carrier Detect. The state of this bit is communicated to the
IrDA Primary device via the IrDA CD bit.
1 = No Carrier Present
0 = Carrier Present
IR RX Photo Detect Diode input. This input signal is required
to be a pulse to indicate an IR bit. When the amplitude of the
signal crosses the amplitude threshold set by the RXPDREF
pin, the IR bit is detected.
