the number of clocks cannot exceed the remaining page length. If more than 256 bytes are sent to the device the

addressing wraps around to the beginning of the page and overwrites previously sent data.

The CS pin must be driven high after the eighth bit of the last byte has been latched. If this is not done, the Page

Program instruction is not executed. After CS is driven high, the self-timed ‘Page Program’ instruction commences for

a time duration of tPP (see Table 8-7, AC Electrical Characteristics). While the page program operation is in progress, the

‘Read Status Register’ instruction may still be accessed for checking the status of the BUSY bit. 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. When the BUSY bit is asserted, the Write Enable Latch (WEL) bit in the Status Register is cleared to
