Detailed operation
Table 10.
1. All bus cycles are WRITE bus cycles, except the ones with the “READ” label
2. All values are in hexadecimal:
3. Only address bits A11-A0 are used in instruction decoding.
4. Sector Select (FS0 to FS7 or CSBOOT0 to CSBOOT3) signals are active high, and are defined in PSDsoft Express.
5. No Unlock or instruction cycles are required when the device is in the READ mode
6. The Reset instruction is required to return to the READ mode after reading the Flash ID, or after reading the Sector
7. The data is 00h for an unprotected sector, and 01h for a protected sector. In the fourth cycle, the Sector Select is active,

Instruction
X = Don’t Care. Addresses of the form XXXXh, in this table, must be even addresses
RA = Address of the memory location to be read
RD = Data read from location RA during the READ cycle
PA = Address of the memory location to be programmed. Addresses are latched on the falling edge of Write Strobe (WR,
CNTL0). 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 Write Strobe (WR, CNTL0)
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).
Protection Status, or if the Error flag bit (DQ5/DQ13) goes high.
