1. Yes in the protocol columns indicates that the command is supported and has the same
functionality and command sequence as other commands marked Yes.
Notes:
2. Address bytes = 0. Dummy clock cycles = 0.
3. Address bytes = 3. Dummy clock cycles default = 8.
4. Address bytes default = 3; address bytes = 4 (extended address). Dummy clock cycles = 0.
5. Address bytes default = 3; address bytes = 4 (extended address). Dummy clock cycles de-
fault = 8. Dummy clock cycles default = 10 (when quad SPI protocol is enabled). Dummy
clock cycles are configurable by the user.
6. Address bytes default = 3; address bytes = 4 (extended address). Dummy clock cycles de-
fault = 6. Dummy clock cycles default = 8 when quad SPI protocol is enabled. Dummy
clock cycles are configurable by the user.
7. Address bytes default = 3; address bytes = 4 (extended address). Dummy clock cycles de-
fault = 8. Dummy clock cycles are configurable by the user.
8. Address bytes = 4. Dummy clock cycles = 0.
9. Address bytes = 4. Dummy clock cycles default = 8. Dummy clock cycles default = 10
(when quad SPI protocol is enabled). Dummy clock cycles are configurable by the user.
10. Address bytes = 4. Dummy clock cycles default = 10. Dummy clock cycles is configurable
by the user.
11. When the device is in dual SPI protocol, the command can be entered with any of these
three codes. The different codes enable compatibility between dual SPI and extended
SPI protocols.
12. When the device is in quad SPI protocol, the command can be entered with any of these
three codes. The different codes enable compatibility between quad SPI and extended
SPI protocols.
13. The WRITE ENABLE command must be issued first before this command can be execu-
ted.
