9-23. Page Program (PP)
The Page Program (PP) instruction is for programming the memory to be "0". A Write Enable (WREN) instruction
must be executed to set the Write Enable Latch (WEL) bit before sending the Page Program (PP). The device pro-
grams only the last 256 data bytes sent to the device. The last address byte (the 8 least significant address bits,
A7-A0) should be set to 0 for 256 bytes page program. If A7-A0 are not all zero, transmitted data that exceed page
length are programmed from the starting address (24-bit address that last 8 bit are all 0) of currently selected page.
If the data bytes sent to the device exceeds 256, the last 256 data byte is programmed at the request page and
previous data will be disregarded. If the data bytes sent to the device has not exceeded 256, the data will be pro-
grammed at the request address of the page. There will be no effort on the other data bytes of the same page.
The sequence of issuing PP instruction is: CS# goes low→ sending PP instruction code→ 3-byte address on SI→ at
least 1-byte on data on SI→ CS# goes high.
The CS# must be kept low during the whole Page Program cycle; The CS# must go high exactly at the byte boundary (the
latest eighth bit of data being latched in), otherwise the instruction will be rejected and will not be executed.
The self-timed Page Program Cycle time (tPP) is initiated as soon as Chip Select (CS#) goes high. The Write in
Progress (WIP) bit still can be checked during the Page Program cycle is in progress. The WIP sets 1 during the
tPP timing, and sets 0 when Page Program Cycle is completed, and the Write Enable Latch (WEL) bit is reset. If the
page is protected by BP3, BP2, BP1, BP0 bits, the Page Program (PP) instruction will not be executed.
Both SPI (8 clocks) and QPI (2 clocks) command cycle can accept by this instruction. The SIO[3:1] are "don't care"
in SPI mode.
