WRITE ALL (WRAL)
The Write All (WRAL) instruction will write the entire
memory array with the data specified in the command.
The WRAL cycle is completely self-timed and com-
mences at the falling edge of the CS, except on ‘C’
devices where the rising edge of CLK before the last
data bit initiates the write cycle. Clocking of the CLK pin
is not necessary after the device has entered the
WRAL cycle. The WRAL command does include an
automatic ERAL cycle for the device. Therefore, the
WRAL
instruction does not require an ERAL instruction
but the chip must be in the EWEN status.
The DO pin indicates the READY/BUSY status of the
device if CS is brought high after a minimum of 250 ns
low (T
CSL).
