USI – Universal Serial Interface
Features
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 signifi-
cantly 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 on
including I/O bits and I/O pins, are shown in bold. The device-specific I/O Register and bit
locations are listed in the
Figure 4-62. Universal Serial Interface, Block Diagram
The 8-bit USI Data Register 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 possi-
ble to ensure that no data is lost. The USI Data Register is a serial shift register and the most
significant bit that is the output of the serial shift register is connected to one of two output pins
depending of the wire mode configuration. A transparent latch is inserted between the USI
Data Register Output and output pin, which 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 independent of the configuration.
