The MCP2122 has up to four signals that can be inter-
faced to the embed ded systems Host Controller. These
signals are the transmitted and received data (TX and
RX), the 16XCLK signal and the RESET signal.
The MCP2122 is pinout compatible with the Agilent

Interfacing the MCP2122 to the Host Controller
Author: Mark Palmer The 16x clock is used for the baud clock timing (trans-
Microchip Technology Inc. mit and receive). There are 16 16x clocks (16XCLK) for
each bit time. In systems that have already been
designed with the HSDL-7000, the 16XCLK signal is
INTRODUCTION already present. For systems that are to be designed,
