Table 311. Registers Used To Program Serial-Bus Devices
PCI OFFSET
REGISTER NAME
DESCRIPTION
B0h
Serial-bus data
(see Section 4.55)
Contains the data byte to send on write commands or the received data byte on read commands.
B1h
Serial-bus word address
(see Section 4.56)
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. Bit 7 (PROT_SEL) in the serial-bus control and status
register (offset B3h, see Section 4.58) is set to 1b to enable the slave address to be sent.
B2h
Serial-bus slave address
(see Section 4.57)
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
(see Section 4.58)
Serial interface enable, busy, and error status are communicated through this register. In
addition, the protocol-select bit (PROT_SEL) and serial-bus test bit (SBTEST) are programmed
through this register.
To access the serial EEPROM through the software interface, the following steps are performed:
1. The control and status byte is read to verify the EEPROM interface is enabled (SBDETECT asserted) and
not busy (REQBUSY and ROMBUSY deasserted).
2. The serial-bus word address is loaded. If the access is a write, then the data byte is also loaded.
3. The serial-bus slave address and R/W command selector byte is written.
4. REQBUSY is monitored until this bit is deasserted.
5. SB_ERR is checked to verify that the serial-bus operation completed without error. If the operation is a
read, then the serial-bus data byte is now valid.
3.7
Advanced Error Reporting Registers
In the extended PCI Express configuration space, the bridge supports the advanced error reporting
capabilities structure. For the PCI Express interface, both correctable and uncorrectable error statuses are
provided. For the PCI bus interface, secondary uncorrectable error status is provided. All uncorrectable status
bits have corresponding mask and severity control bits. For correctable status bits, only mask bits are
provided.
Both the primary and secondary interfaces include first error pointer and header log registers. When the first
error is detected, the corresponding bit position within the uncorrectable status register is loaded into the first
error pointer register. Likewise, the header information associated with the first failing transaction is loaded
into the header log. To reset this first error control logic, the corresponding status bit in the uncorrectable status
register is cleared by a writeback of 1b.
For systems that require high data reliability, ECRC is fully supported on the PCI Express interface. The
primary side advanced error capabilities and control register has both ECRC generation and checking enable
control bits. When the checking bit is asserted, all received TLPs are checked for a valid ECRC field. If the
generation bit is asserted, then all transmitted TLPs contain a valid ECRC field.
3.8
Data Error Forwarding Capability
The bridge supports the transfer of data errors in both directions.
If a downstream PCI Express transaction with a data payload is received that targets the internal PCI bus and
the EP bit is set indicating poisoned data, then the bridge must ensure that this information is transferred to
the PCI bus. To do this, the bridge forces a parity error on each PCI bus data phase by inverting the parity bit
calculated for each double-word of data.
If the bridge is the target of a PCI transaction that is forwarded to the PCI Express interface and a data parity
error is detected, then this information is passed to the PCI Express interface. To do this, the bridge sets the
EP bit in the upstream PCI Express header.
