I
Boot sequencer mode also supports an extension of the standard I
to allow for EEPROM devices that have more than 256 bytes. This extended addressing mode is selectable
using a different encoding in the BOOTSEQ field of the high-order reset configuration word (see
Section 4.3.2.2.3, “Boot Sequencer
and the maximum number of registers is limited by the size of the EEPROM.
If the standard I
Then it issues a repeated start and addresses the next EEPROM address. This sequence continues until the
CONT bit is cleared. If the last register is not detected before wrapping back to the first address, an error
condition is detected. In other words, if the CONT bit for not cleared on the final 7 bytes, an error condition
is detected, causing the I
long as the continue (CONT) bit is set in the EEPROM. The CONT bit resides in the address/attributes
field that is transferred from the EEPROM, as described in

Note that this usage does not prevent using the I
functional mode, after reset state has completed. However, an I
type must be used and the first two EEPROM data structures must contain dedicated reset information.
17.4.5.2
The EEPROM calling address is 0b101_0000. The first EEPROM to be addressed must be programmed
to respond to this address, or an error is generated. Any additional EEPROMs are addressed in sequential
order.
