Interfacing The MCP215X to a Host Controller
This application note discusses the operation of the MCP215X Host UART interface, implements an embedded system (as an IrDA® Standard Secondary device), and describes the setup of Personal Digital Assistants (PDA) devices to operate as the IrDA Standard Primary device.
The Host UART interface includes non-data Flow Control signals. These are the signals between a Host Controllerand a MCP215X device (see Figure 1). References in this document to the MCP215X device mean either the MCP2150 device or the MCP2155 device.
The embedded system is comprised of an Optical Transceiver circuit, a MCP215X device and a Host Controller (PIC16F87X). This typical embedded system implementation is shown in Figure 1.
