Description
High byte of the
microcontroller address bus.
An external pull-up on the A11
pin causes the serial ROM
download to use the 2-wire
serial interface 1. If no
external pull-up is used the
download will use the 2-wire
serial interface 0.
A[10:8] are used to select a
chip address for the serial
ROM. For more information on
the possible addresses, see
Table
For more information on these
power-up options, see
Chapter
Low byte of the
microcontroller multiplexed
address/data bus.
An external pull-up on AD[1:0]
enables automatic branch
generation. For information on
the branch values, see
Table
An external pull-up on AD5
causes the LSI53C040 to
download firmware from a
serial ROM at power on.

power-up options, see
