Table 8. Instructions
X
RA = Address of the memory location to be read.
RD = Data read from location RA during read operation.
PA = Address of the memory location to be programmed. Addresses are latched on the falling edge of the WR#
(CNTL0) pulse. PA is an even address for PSD in word programming mode.
PD = Data (word) to be programmed at location PA. Data is latched on the rising edge of WR# (CNTL0) pulse.
SA = Address of the sector to be erased or verified. The chip select (FS0-7 or CSBOOT0-3) of the sector to be
erased must be active (high).
= Don’t Care. “xxxh” address in the above table must be an even address.
NOTES:
1.
All bus cycles are write bus cycle except the ones with the “read” label.
2.
All values are in hexadecimal.
3.
FS0-7 and CSBOOT0-3 are active high and are defined in PSDsoft.
4.
Only Address bits A11-A0 are used in Instruction decoding.
5.
No unlock or command cycles required when device is in read mode.
6.
The Reset command is required to return to the read mode after reading the Flash ID, Sector Protect status
or if DQ5 (DQ13) goes high.
7.
Additional sectors to be erased must be entered within 80μs.
8.
The data is 00h for an unprotected sector and 01h for a protected sector. In the fourth cycle, the sector chip
select is active and (A1 = 1, A0 = 0).
9.
The Unlock Bypass command is required prior to the Unlock Bypass Program command.
10. The Unlock Bypass Reset command is required to return to reading array data when the device is in the
Unlock Bypass mode.
11. The system may read and program functions in non-erasing sectors, read the Flash ID or read the Sector
Protect status, when in the Erase Suspend mode. The erase Suspend command is valid only during a sector
erase operation.
12. The Erase Resume command is valid only during the Erase Suspend mode.
13. The MCU cannot invoke these instructions while executing code from the same Flash memory for which the
instruction is intended. The MCU must fetch, for example, codes from the Secondary Flash memory when
reading the Sector Protection Status of the main Flash.
14. All write bus cycles in an instruction are byte write to even address (XA4Ah or X554h). Flash Programming
bys cycle is writing a word to even address.
