TCAR

Target

Configuration

Access Ready

Target Configuration Access Ready (Default: 0x0/0x1)

Specifies whether to accept PCI access as a target.

PCI controller receives a target access, when this bit is 1 and

PCISTATUS.E2PDONE bit is 1.

Configuration access from the PCI Bus can be accepted during PCI Boot

up after initialization from EEPROM or after each initialization ends. Please

use the software to set this bit after initialization ends. Retry response to

PCI configuration access is performed until this bit is set.

This bit becomes “1” only when in the PCI Boot Mode and the Satellite

Mode. Operation when this bit is set to “1” then reset to “0” is not defined.

1: Responds to PCI target access.

0: Performs a Retry response to PCI target access.

R/W

ICAEN

Initiator

Configuration

Access Enable

Initiator Configuration Access Enable (Default: 0x1)

Controls initiator PCI configuration access using the G2P Configuration

Address Register (G2PCFGADRS) and the G2P Configuration Data

1: Initiator configuration access is possible.

0: Initiator configuration access is not possible.

R/W

LCFG

Load

Configuration

Data Register

Load PCI Configuration Data Register (Default: 0x0)

When a software reset is performed on this bit using the Software Reset bit

(PCICFG.SRST) when this bit is already set, data is loaded to the

Configuration Space Register from the Configuration Data 0/1/2/3 Register.

1: Load from the Configuration Data 0/1/2/3 Register.

0: Load from EEPROM.
