Indicates the busy state of the EEPROM interface
0: The EEPROM interface is idle
1: The EEPROM interface is busy
Indicates the write enable error
0: No error
1: Write command without write enable
Indicates the acknowledge/command error
0: No error
1: Missing EEPROM acknowledge or invalid command
Indicates the EEPROM loading status
0: EEPROM loaded, device information has no error
1: EEPROM not loaded, device information not available (EEPROM loading in progress or
finished with a failure)
Indicates the checksum error in the ESC configuration area
0: Checksum has no error
1: Checksum error

Command
Write: Initiates the command below
Read: Indicates the currently executed command
Commands:
000: No command/EEPROM idle (clear error bits)
001: Read
010: Write
100: Reload
Others: Reserved/invalid commands (do not issue)
Indicates the selected EEPROM algorithm
0: 1 address byte (1 Kbit – 16 Kbit EEPROMs)
1: 2 address bytes (32 Kbit – 4 Mbit EEPROMs)
Indicates the supported number of EEPROM read bytes
0: 4 bytes
1: 8 bytes
Note2
ECAT Write Enable
0: Write requests are disabled
1: Write requests are enabled
This bit is always 1 if PDI has EEPROM control.
