SMC91C100 Datasheet, PDF (34/83 Pages) List of Unclassifed Manufacturers – FEAST Fast Ethernet Controller

Note: When an EEPROM access is in progress
the STORE and RELOAD bits will be read back
as high. The remaining 14 bits of this register
will be invalid. During this time attempted
read/write operations, other than polling the
EEPROM status, will NOT have any effect on
the internal registers. The CPU can resume
accesses to the SMC91C100 after both bits are
low. A worst case RELOAD operation initiated by
RESET or by software takes less than 750µsec.
