IR Receive Photo Detect Diode reference voltage. This
voltage will typically be in the range of V
DD
/2.
Asynchronous transmit to IrDA transceiver.
Protocol Handler Active. Indicates the state of the MCP2140
Protocol Handler. This output is an open collector, so an
external pull-up resistor may be required.
1
= Protocol Handler is in the Discovery or NRM state
0
= Protocol Handler is in NDM state or the MCP2140 is
in Low Power mode
Resets the Device
Ground reference for logic and I/O pins
No connect
Asynchronous receive; from Host Controller UART
Asynchronous transmit; to Host Controller UART
Ring Indicator. The state of this bit is communicated to the
IrDA Primary Device.
1
= No Ring Indicate Present
0
= Ring Indicate Present
Data Set Ready. Indicates that the MCP2140 has estab-
lished a valid IrDA link with a Primary Device
(1)
. This signal
is locally emulated and not related to the DTR bit of the IrDA
Primary Device.
1
= An IR link has not been established
(No IR Link)
0
= An IR link has been established (IR Link)
Data Terminal Ready. Indicates that the Embedded device
connected to the MCP2140 is ready for IR data. The state of
this bit is communicated to the IrDA Primary Device via the
IrDA DSR bit carried by IrCOMM.
1
= Embedded device not ready
0
= Embedded device ready
Clear to Send. Indicates that the MCP2140 is ready to
receive data from the Host Controller. This signal is locally
emulated and not related to the CTS/RTS bit of the IrDA
Primary Device.
1
= Host Controller should not send data
0
= Host Controller may send data
