Notes to
(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
(4) Read silicon ID operation is available only for EPCS1, EPCS4, EPCS16, and EPCS64.
(5) Read Device Identification operation is available only for EPCS128.

Write Enable Operation
The write enable operation code is b'0000 0110, and the MSB 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.
