19.2.1
TWI Terminology
The following definitions are frequently encountered in this section.
The Power Reduction TWI bit, PRTWI bit in “PRR – Power Reduction Register” on page 47 must
be written to zero to enable the 2-wire Serial Interface.
19.2.2
Electrical Interconnection
As depicted in Figure 19-1, both bus lines are connected to the positive supply voltage through
pull-up resistors. The bus drivers of all TWI-compliant devices are open-drain or open-collector.
This implements a wired-AND function which is essential to the operation of the interface. A low
level on a TWI bus line is generated when one or more TWI devices output a zero. A high level
is output when all TWI devices trim-state their outputs, allowing the pull-up resistors to pull the
line high. Note that all AVR devices connected to the TWI bus must be powered in order to allow
any bus operation.
The number of devices that can be connected to the bus is only limited by the bus capacitance
limit of 400 pF and the 7-bit slave address space. A detailed specification of the electrical char-
acteristics of the TWI is given in “SPI Timing Characteristics” on page 333. Two different sets of
specifications are presented there, one relevant for bus speeds below 100 kHz, and one valid for
bus speeds up to 400 kHz.
19.3
Data Transfer and Frame Format
19.3.1
Transferring Bits
Each data bit transferred on the TWI bus is accompanied by a pulse on the clock line. The level
of the data line must be stable when the clock line is high. The only exception to this rule is for
generating start and stop conditions.
