Configuration Handbook, Volume 2
Serial Configuration Devices (EPCS1, EPCS4, EPCS16 & EPCS64) Data Sheet
All attempts to access the memory contents while a write or erase cycle is
in progress will not be granted, and the write or erase cycle will continue
unaffected.
Write Enable Operation
The write enable operation code is
b'0000 0110
, and the most
significant bit is listed 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 4–5
shows the timing diagram for the write
enable operation.
Figures 4–7
and
4–8
show the status register bit
definitions.

Notes to
Table 4–8
:
(1)
The MSB is listed first and the least significant bit (LSB) is listed last.
(2)
The status register, data or silicon ID are read out at least once on the
DATA
pin and will continuously be read out
until
nCS
is driven high
(3)
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.
