Description
To erase a sector of a Micron 2 gigabit (Gb) flash at address 0x04FF0000 using the
QSPI_WRITE_DEVICE_REG command, write the flash address in MSB to LSB order as shown
here:
Header: 0x00003036
Opcode: 0x000000DC
Number of bytes to write: 0x00000004
Flash address: 0x0000FF04
A successful write returns the OK response code. This command pads data that is not a multiple
of 4 bytes to the next word boundary.
QSPI_SEND_DEVICE_
OP
37 1 0 Sends a command opcode to the quad SPI. Takes one argument:
• The opcode to send the quad SPI device.
A successful command returns the OK response code.
RSU_NOTIFY
5D 1 0
Clears all error information in the RSU_STATUS response and resets the retry counter. The one-
word argument has the following fields:
• 0x00050000: Clear current reset retry counter. Resetting the current retry counter sets the
counter back to zero, as if the current image was successfully loaded for the first time.
• 0x00060000: Clear error status information.
• All other values are reserved.
This command is not available before version 19.3 of the Intel Quartus Prime Pro Edition
Software.
