Figure 46. Read OTP instruction and data-out sequence DIO-SPI
Write Enable (WREN)
The Write Enable (WREN) instruction sets the Write Enable Latch (WEL) bit.
Apart form the parallelizing of the instruction code on the two pins DQ0 and DQ1, the
instruction functionality is exactly the same as the Write Enable (WREN) instruction of the
Extended SPI protocol.
Figure 47. Write Enable instruction sequence DIO-SPI
Write Disable (WRDI)
The Write Disable (WRDI) instruction resets the Write Enable Latch (WEL) bit.
Apart form the parallelizing of the instruction code on the two pins DQ0 and DQ1, the
instruction functionality is exactly the same as the Write Disable (WRDI) instruction of the
Extended SPI protocol, please refer to
details.
