Three-wire Mode
2543L–AVR–08/10
The Two-wire clock control unit can generate an interrupt when a start condition is detected on
the Two-wire bus. It can also generate wait states by holding the clock pin low after a start con-
dition is detected, or after the counter overflows.
The USI Three-wire mode is compliant to the Serial Peripheral Interface (SPI) mode 0 and 1, but
does not have the slave select (SS) pin functionality. However, this feature can be implemented
in software if necessary. Pin names used by this mode are: DI, DO, and USCK.
Figure 61. Three-wire Mode Operation, Simplified Diagram
Figure 61
The two Shift Registers are interconnected in such way that after eight USCK clocks, the data in
each register are interchanged. The same clock also increments the USI’s 4-bit counter. The
Counter Overflow (interrupt) Flag, or USIOIF, can therefore be used to determine when a trans-
fer is completed. The clock is generated by the Master device software by toggling the USCK pin
via the PORT Register or by writing a one to the USITC bit in USICR.
