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#
PD = Data to be programmed at location PA. Data is latched o 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
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. A15-12 (or A16-A12) are don’t care.
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
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
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
11. The system may read and program functions in non-erasing sectors, read the Flash ID or read the Sector
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
