PCI OFFSET
REGISTER NAME
DESCRIPTION
B0h
Serial-bus data
Contains the data byte to send on write commands or the received data byte on read commands.
B1h
Serial-bus index
The content of this register is sent as the word address on byte writes or reads. This register is not used
in the quick command protocol.
B2h
Serial-bus slave
address
Write transactions to this register initiate a serial-bus transaction. The slave device address and the
R/W command selector are programmed through this register.
B3h
Serial-bus control
and status
Read data valid, general busy, and general error status are communicated through this register. In
addition, the protocol-select bit is programmed through this register.
3.6.3
Serial-Bus Interface Protocol
The SCL and SDA signals are bidirectional, open-drain signals and require pullup resistors as shown in Figure 33.
The PCI6x21/PCI6x11 controller, which supports up to 100-Kb/s data-transfer rate, is compatible with standard mode
I
2
C using 7-bit addressing.
All data transfers are initiated by the serial bus master. The beginning of a data transfer is indicated by a start
condition, which is signaled when the SDA line transitions to the low state while SCL is in the high state, as shown
in Figure 36. The end of a requested data transfer is indicated by a stop condition, which is signaled by a low-to-high
transition of SDA while SCL is in the high state, as shown in Figure 36. Data on SDA must remain stable during the
high state of the SCL signal, as changes on the SDA signal during the high state of SCL are interpreted as control
signals, that is, a start or a stop condition.

Figure 36. Serial-Bus Start/Stop Conditions and Bit Transfers
Data is transferred serially in 8-bit bytes. The number of bytes that may be transmitted during a data transfer is
unlimited; however, each byte must be completed with an acknowledge bit. An acknowledge (ACK) is indicated by
the receiver pulling the SDA signal low, so that it remains low during the high state of the SCL signal. Figure 37
illustrates the acknowledge protocol.
