7.2.28 Erase / Program Resume (7Ah)
The Erase/Program Resume instruction “7Ah” must be written to resume the Sector or Block Erase
operation or the Page Program operation after an Erase/Program Suspend. The Resume instruction
“7Ah” will be accepted by t he device only if the SUS bit in the Status Register equals to 1 and the BUSY
bit equals to 0. After issued the SUS bit will be cleared from 1 to 0 immediately, the BUSY bit will be set
from 0 to 1 within 200ns and the Sector or Block will complete the erase operation or the page will
complete the program operation. If the SUS bit equals to 0 or the BUSY bit equals to 1, the Resume
instruction “ 7A h” will be ignored by the device. The Erase/Program Resume instruction sequence is
shown in Figure 26.
Resume instruction is ignored if the previous Erase/Program Suspend operation was interrupted by
unexpected power off. It is also required that a subsequent Erase/Program Suspend instruction not to be
issued within a minimum of time of “t SUS ” following a previous Resume instruction.
