Write Enable Operation
The write enable operation code is b'0000 0110, and it lists the MSB first. The write
enable operation sets the write enable latch bit, which is bit 1 in the status register.
Always set the write enable latch bit before write bytes, write status, erase bulk, and
erase sector operations. Figure 5 shows the instruction sequence of the write enable
operation.
Write Disable Operation
The write disable operation code is b'0000 0100 and it lists the MSB first. The write
disable operation resets the write enable latch bit, which is bit 1 in the status register.
To prevent the memory from being written unintentionally, the write enable latch bit
is automatically reset when implementing the write disable operation, and under the
following conditions:
■
Power up
■
Write bytes operation completion
■
Write status operation completion
■
Erase bulk operation completion
■
Erase sector operation completion

Notes to Table 8:
(1) List MSB first and LSB last.
(2) The status register, data, or silicon ID is read out at least once on the DATA pin and is continuously read out until the nCS pin is driven high.
(3) A write bytes operation requires at least one data byte on the DATA pin. If more than 256 bytes are sent to the device, only the last 256 bytes
are written to the memory.
(4) The read silicon ID operation is available only for EPCS1, EPCS4, EPCS16, and EPCS64 devices.
(5) The read device identification operation is available only for EPCS128 devices.
