Overview

The Universal Serial Interface, or USI, provides the basic hardware resources needed for serial
communication. Combined with a minimum of control software, the USI allows significantly
higher transfer rates and uses less code space than solutions based on software only. Interrupts
are included to minimize the processor load.
A simplified block diagram of the USI is shown in

Register and bit locations are listed in the
Figure 13-1. Universal Serial Interface, Block Diagram
The 8-bit USI Data Register (USIDR) is directly accessible via the data bus and contains the
incoming and outgoing data. The register has no buffering so the data must be read as quickly
as possible to ensure that no data is lost. The data register is a serial shift register where the
most significant bit is connected to one of two output pins depending of the wire mode configura-
tion. A transparent latch between the output of the data register and the output pin delays the
change of data output to the opposite clock edge of the data input sampling. The serial input is
always sampled from the Data Input (DI) pin, regardless of the configuration.
