FLASH Memory
There are 4096 bytes of programmable/erasable FLASH
memory for CPU program instructions and coefficients
storage. In addition, there are 128 bytes of FLASH mem-
ory accessible only by the serial interface for storage of
user information data.
These two FLASH memory locations are separated as
partitions. The program/coefficient memory is FLASH
partition 0 and the information memory is FLASH parti-
tion 1. Each partition is accessible by the serial inter-
face for reading, erasing, and writing data. Program/
coefficient memory partition 0 is accessible by the CPU
as read only, and partition 1 is not accessible by the
CPU. The CPU cannot erase or write data to either of
the FLASH memory partitions.
FLASH partition 0 is selected during the POR cycle.
FLASH partition 1 is selected by sending the halt CPU
command (IRS[7:0] = 78h) and changing the partition
selected by sending the change partition command
(IRS[7:0] = F8h). A following halt command (IRS[7:0] =
78h) resets the selected partition to partition 0.
Modifying the FLASH Contents
The MAX1464 FLASH memory contents must be erased
(contents = FFh) before the desired contents can be writ-
ten. There is no individual byte-erase command, but
either a total-erase command (IRS[7:0] = E8h) where all
the selected partition is erased (4kB for partition 0 or 128
bytes for partition 1) or a page-erase command (IRS[7:0]
= D8h), where only 64 bytes are erased, and the page is
selected by PFAR[11:6]. There are 64 pages in FLASH
partition 0, and only 2 pages in FLASH partition 1.
The programming of the MAX1464 FLASH memory
must use the following procedure (all the commands
are to be sent through the serial interface, and are
hexadecimal values of IRS[7:0]):
