Dual Command Page Program (DCPP)
The Dual Command Page Program (DCPP) instruction allows to program the memory
content in DIO-SPI protocol, parallelizing the instruction code, the address and the input
data on two pins (DQ0 and DQ1). Before it can be accepted, a Write Enable (WREN)
instruction must previously have been executed. The Dual Command Page Program
(DCPP) instruction can be issued, when the device is set in DIO-SPI mode, by sending to
the memory indifferently one of the 3 instructions codes: 02h, A2h or D2h, the effect is
exactly the same. The 3 instruction codes are all accepted to help the application code
porting from Extended SPI protocol to DIO-SPI protocol.
Apart for the parallelizing on two pins of the instruction code, the Dual Command Page
Program instruction functionality is exactly the same as the Dual Input Extended Fast
Program of the Extended SPI protocol, please refer to
