8.2.12 Quad Load Program Data (32h) / Quad Random Load Program Data (34h)
The âQuad Load Program Dataâ and âQuad Random Load Program Dataâ instructions are identical to the
âLoad Program Dataâ and âRandom Load Program Dataâ in terms of operation sequence and functionality.
The only difference is that âQuad Loadâ instructions will input the data bytes from all four IO pins instead of
the single DI pin. This method will significantly shorten the data input time when a large amount of data
needs to be loaded into the Data Buffer. The instruction sequence is illustrated in Figure 16.
Both âQuad Load Program Dataâ and âQuad Random Load Program Dataâ instructions share the same
command sequence. The difference is that âQuad Load Program Dataâ instruction will reset the unused the
data bytes in the Data Buffer to FFh value, while âQuad Random Load Program Dataâ instruction will only
update the data bytes that are specified by the command input sequence, the rest of the Data Buffer will
remain unchanged.
When WP-E bit in the Status Register is set to a 1, all Quad SPI instructions are disabled.
