1.
All bus cycles are WRITE bus cycles, except the ones with the “Read” label
2.
All values are in hexadecimal.
3.
X = Don’t care. Addresses of the form XXXXh, in this table, must be even addresses
4.
RA = Address of the memory location to be read
5.
RD = Data READ from location RA during the READ cycle
6.
PA = Address of the memory location to be programmed. Addresses are latched on the falling edge of
WRITE Strobe (WR, CNTL0).
7.
PA is an even address for PSD in Word Programming mode.
8.
PD = Data word to be programmed at location PA. Data is latched on the rising edge of WRITE Strobe
(WR, CNTL0)
9.
SA = Address of the sector to be erased or verified. The Sector Select (FS0-FS7 or CSBOOT0-CSBOOT3)
of the sector to be erased, or verified, must be Active (High).
10. Sector Select (FS0-FS7 or CSBOOT0-CSBOOT3) signals are active High, and are defined in PSDsoft
Express.
11. Only address Bits A11-A0 are used in instruction decoding.
12. No Unlock or instruction cycles are required when the device is in the READ mode
13. The RESET instruction is required to return to the READ mode after reading the Sector Protection Status,
or if the Error flag bit (DQ5/DQ13) goes High.
14. Additional sectors to be erased must be written at the end of the Sector Erase instruction within 80s.
15. The data is 00h for an unprotected sector, and 01h for a protected sector. In the fourth cycle, the Sector
Select is active, and (A1,A0)=(1,0)
16. The Unlock Bypass instruction is required prior to the Unlock Bypass Program instruction.
17. The Unlock Bypass Reset Flash instruction is required to return to reading memory data when the device is
in the Unlock Bypass mode.
18. The system may perform READ and Program cycles in non-erasing sectors, read the Flash ID or read the
Sector Protection Status when in the Suspend Sector Erase mode. The Suspend Sector Erase instruction
is valid only during a Sector Erase cycle.
19. The Resume Sector Erase instruction is valid only during the Suspend Sector Erase mode.
