Preliminary
ERAL
The ERAL instruction erases the entire 256 8 memory
cells to a logical 1 state in the programming enable
mode. After the erase-all instruction set has been is-
sued, the data erase feature is activated by a falling
edge of CS. Since the internal auto-timing generator
provides all timing signal for the erase-all operation, so
theSKclockisnotrequired.Duringtheinternalerase-all
operation, we can verify the busy/ready status if CS is
high. The DO will remain low but when the operation is
over, the DO will return to high and further instruction
can be executed.
WRAL
The WRAL instruction writes data into the entire 256 8
memory cells in the programming enable mode. After
the write-all instruction set has been issued, the data
writing is activated by a falling edge of CS. Since the in-
ternal auto-timing generator provides all timing signals
for the write-all operation, so the SK clock is not re-
quired. During the internal write-all operation, we can
verify the busy/ready status if CS is high. The DO will re-
main low but when the operation is over the DO will re-
turn to high and further instruction can be executed.
