Request to Send. Indicates that a Host Controller is ready to
receive data from the MCP2140. This signal is locally emu-
lated 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.
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
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. The pulse has minimum and max-
imum requirements as specified in
Oscillator crystal output.
IR RX Photo Detect Diode input. This input signal is required
