In addition to the signals described in Tables 2-10 through 2-12, the MCP215X RESET
input is connected to the RESET output of the Host Controller (PIC16F877 I/O pin
RC0), which asserts low after the RESET push button switch is asserted and the OSC1
and OSC2 pins are connected to an external 11.0592 MHz oscillator; specified in the
MCP2150 data sheet (DS21655) and the MCP2155 data sheet (DS21690)

MCP215X OPERATION
The MCP215X (U3) implements the 9-wire “cooked” service class in the IrCOMM Appli-
cation Layer protocol of the IrDA standard specification. IrCOMM is the IrDA standard
specification for the replacement of the communication ports (serial and parallel) of a
PC. The MCP215X allows the replacement of the serial cable with a wireless interface.
The MCP215X implements the entire protocol layer, while the Host Controller
(PIC16F877) talks to the MCP215X as if it were a serial port with flow control.
The MCP215X operates as a Secondary device only, so it will not initiate IrDA standard
communication with other IrDA standard devices (neither a Secondary or Primary
device).
sequence between a Primary device and the MCP215X (Secondary device). This
connection sequence is shown at an overview level and does not show exact
operation.
