Page Program (PP)
The Page Program instruction allows many bytes to be
programmed in the memory. The bytes must be in the erased
state (FFH) when initiating a Program operation. A Page
Program instruction applied to a protected memory area will be
ignored.
Prior to any Write operation, the Write Enable (WREN) instruction
must be executed. CE must remain active low for the duration
of the Page Program instruction. The Page Program instruction is
initiated by executing an 8-bit command, 02H, followed by
address bits [A
Data is input (the maximum of input data can be up to 256 bytes).
If the 8 least significant address bits [A

are programmed from the start address of the same page (from

latched data are discarded and the last 256 bytes Data are
guaranteed to be programmed correctly within the same page. If
less than 256 bytes Data are sent to device, they are correctly
programmed at the requested addresses without having any
effects on the other bytes of the same page.

Status Register instruction may still be accessed for checking the
status of the BUSY bit. It is recommended to wait for a duration of
T
The BUSY bit is a 1 during the Page Program cycle and becomes
a 0 when the cycle is finished and the device is ready to accept
other instructions again. After the Page Program cycle has
finished, the Write-Enable-Latch (WEL) bit in the Status Register
is cleared to 0. See Figure 10 for the Page Program sequence.
