Description
RXPDREF
1
I
A
IR Receive Photo Detect Diode reference voltage. This
voltage will typically be in the range of VDD/2.
TXIR
2
O
—
Asynchronous transmit to IrDA transceiver.
PHACT
3
OC
—
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
RESET

I
ST
Resets the Device
VSS

P
Ground reference for logic and I/O pins
NC

I
TTL
Asynchronous receive; from Host Controller UART
RX

Asynchronous transmit; to Host Controller UART
RI

10
I
TTL
Ring Indicator. The state of this bit is communicated to the
IrDA Primary Device.
1
= No Ring Indicate Present
0
= Ring Indicate Present
DSR
10
11
O
—
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)
DTR
11
12
I
TTL
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
CTS
12
13
O
—
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
Legend:
TTL = TTL compatible input
ST = Schmitt Trigger input with CMOS levels
A = Analog
P = Power
CMOS = CMOS compatible input
OC = Open collector output
I = Input
O = Output
1: The state of the DTR output pin does not reflect the state of the DTR bit of the IrDA Primary Device.
