This command is also supported in Quad All mode. In Quad AIl mode the instruction is shifted in on IO0-IO3, two clock cycles per
byte. The ECC read command is not supported for 0 dummy latency in Quad All mode.

Write VDLR (WVDLR 4Ah)
Before the Write VDLR (WVDLR) command can be accepted by the device, a Write Enable (WREN) command must be issued and
decoded by the device. After the Write Enable (WREN) command has been decoded successfully, the device will set the Write
Enable Latch (WEL) to enable WVDLR operation.
The WVDLR command is entered by shifting the instruction and the data byte on SI.
CS# must be driven to the logic high state after the eighth (8th) bit of data has been latched. If not, the WVDLR command is not
executed. As soon as CS# is driven to the logic high state, the WVDLR operation is initiated with no delays. The maximum clock
frequency for the PNVDLR command is 133 MHz.
