Ring Indicator. The state of this bit is
communicated to the IrDA
device.
1 = No Ring Indicate Present
0 = Ring Indicate Present
Data Set Ready. Indicates that the MCP2140 has
established a valid infrared link with a Primary
device. This signal is locally emulated and not
related to the DTR bit of the IrDA standard Primary
device. (Note 1)
1 = An IR link has not been established
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 standard 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 form the Host Controller. This
signal is locally emulated and not related to the
CTS/RTS bit of the IrDA standard Primary device.
1 = Host Controller should not send data
0 = Host Controller may send data
Request to Send. Indicates that a Host Controller is
ready to receive data from the MCP2140. This
signal is locally emulated and not related to the
CTS/RTS bit of the IrDA standard Primary device.
1 = Host Controller not ready to receive data
0 = Host Controller ready to receive data
Carrier Detect. The state of this bit is
communicated to the IrDA standard Primary device
via the IrDA standard CD bit.
1 = No Carrier Present
0 = Carrier Present
(No IR Link)
