Field Name
Figure 10.4.42 PCI Controller Status Register (2/2)
Initiator Write Busy (Busy: 0x0)
Indicates that a Write cycle was in progress when a Write cycle to the PCI
Bus was executed.
While a Write cycle is in progress, no error status to that Write cycle is
reflected. Therefore, this bit is used to confirm the status when it changes
from “1” to “0” after the Write cycle ends.
1: Indicates that a Write cycle is in progress.
0: Indicates that no Write cycle is in progress.
EEPROM Load Done (Default--)
When using EEPROM, this bit indicates that data loading from EEPROM is
complete. This bit is set to “1” when the internal process ends even if no
EEPROM is connected.
1: Indicates that data loading from EEPROM is complete.
0: Indicates that data loading from EEPROM is not complete.
