MCP215X IrDA ? PROTOCOL STACK CONTROLLER DEVICE
The key signals for the MCP2150-to-microcontroller (Host UART) interface are shown
in Table 2-6, while Table 2-7 shows the same signals for the MCP2155. The operation
of the Host UART interface is slightly different for the MCP2150 and the MCP2155.
The key signals for the MCP215X-to-IR transceiver circuit are shown in Table 2-8.

Description
Asynchronous receive; from Host Controller UART.
Asynchronous transmit; to Host Controller UART.
Ring Indicator. The value on this pin is driven high.
Data Set Ready. Indicates that the MCP2150 has
completed reset:
1 = MCP2150 is initialized.
0 = MCP2150 is not initialized.
DTR
12
I
TTL
Data Terminal Ready. The value of this pin is
ignored once the MCP2150 is initialized. It is
recommended that this pin be connected so that
the voltage level is either V SS or V CC .
At device power-up, this signal is used with the
RTS signal to enter device ID programming.
1 = Enter device ID programming mode
(if RTS is cleared).
0 = Do not enter device ID programming mode.
CTS
13
O
—
Clear-to-Send. Indicates that the MCP2150 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 ? standard Primary device.
1 = Host Controller should not send data.
0 = Host Controller may send data.
RTS
14
I
TTL
Request-to-Send. Indicates that a Host Controller
is ready to receive data from the MCP2150. 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.
At device power-up, this signal is used with the
DTR signal to enter device ID programming.
1 = Do not enter device ID programming mode.
0 = Enter device ID programming mode
(if DTR is set).
CD
19
I
ST
Carrier Detect. Indicates that the MCP2150 has
established a valid link with a Primary Device.
1 = An IR link has not been established
(No IR Link).
0 = An IR link has been established (IR link).
