8 Defines an enumerated data type called w0_rcr. The if_el device
driver can assign one of the following bits to W0_RCR (the resource
configuration register):
RCR_IRQ Represents the interrupt request (IRQ).
RCR_RSV Represents a reserved field.
9 Defines the offset for the EEPROM command register.
10 Defines an enumerated data type called w0_ecr. The if_el device
driver can assign one of the following bits to W0_ECR (the EEPROM
command register):
ECR_EBY Indicates that the EEPROM is busy.
ECR_TST Indicates that the EEPROM is in test mode.
ECR_CMD Represents EEPROM command bits.
ECR_READ Represents an EEPROM read command.
ECR_WRITE Represents an EEPROM write command.
ECR_ERASE Represents an EEPROM erase command.
ECR_EWENA Represents an EEPROM enable erase or
write command.
ECR_EWDIS Represents an EEPROM disable erase or
write command.
ECR_EAR Represents an EEPROM erase all registers command.
ECR_WAR Represents an EEPROM write all registers command.
11 Defines the offset for the EEPROM data register.
