DATASHEET
WRAL (Write All):
If erase/write operations are enabled in the EEPROM, this command will cause the
contents of the E2P_DATA register to be written to every EEPROM memory location. The EPC_TO bit
is set if the EEPROM does not respond within 30ms.
Figure 3.10 EEPROM WRAL Cycle
Table 3.8, "Required EECLK Cycles"
, shown below, shows the number of EECLK cycles required for
each EEPROM operation.
3.9.2.2
MAC Address Reload
The MAC address can be reloaded from the EEPROM via a host command to the E2P_CMD register.
If a value of 0xA5h is not found in the first address of the EEPROM, the EEPROM is assumed to be
un-programmed and MAC Address Reload operation will fail. The “MAC Address Loaded” bit indicates
a successful load of the MAC address. The EPC_LOAD bit is set after a successful reload of the MAC
address.
3.9.2.3
EEPROM Command and Data Registers
Refer to
Section 5.3.23, "E2P_CMD – EEPROM Command Register," on page 89
and
Section 5.3.24,
"E2P_DATA – EEPROM Data Register," on page 91
for a detailed description of these registers.
Supported EEPROM operations are described in these sections.
3.9.2.4
EEPROM Timing
Refer to
Section 6.9, "EEPROM Timing," on page 119
for detailed EEPROM timing specifications.
