ACL: Lowest Significant Byte of Address Counter.
ACH: 2
nd
Byte of Address Counter.
ACP: Most Significant Byte of Address Counter.
DNLD: Switch the bus to download bus.
RD: Read pulse control.
WR: Write pulse control.
After address setup, the data can be written to address device through EXMD register. Program must
generate the required write pulse by firmware. The address counter AC will automatically increment with
each read/write access.
The procedure for downloading data from I/O or any other sources, i.e. command mode ROM device is as
follows:
1.
2.
3.
Switch the external memory to download bus by setting the DNLD bit of EXMC register.
Make a dummy read to EXMD register to reset the AC pointer.
Set up the address for transferring data by first writing to ACL, and then ACH and ACP with the first
3 writes to register.
Start writing to addressed device by first writing 1 byte of data to EXMD register, clear WR bit of
CMD register and set it again, the AC will increment with each write pulse.
To read addressed device, clear RD bit of EXMC register, read EXMD register and set RD bit again.
The AC will also increment with each read pulse. Read back for verification is optional. Please note
that read back can also be made through external address and data bus when the bus is switched back
to program bus.
Switch back to normal bus for program execution and data access by clearing the DNLD bit of
EXMC register.
4.
5.
6.
Please note that NOR FLASH memory from different manufacturers such as Intel, AMD, SST, etc.
requires various command sequence to set up. Programmer still needs to follow the respective
specifications of the vendors.
