READ
Read operations and instructions can be used to:
– read the contents of the Memory Array (Flash
and EEPROM)
– read the status bits and identifiers.
Read data (Flash and EEPROM)
Both Chip Enable EF (or EE) and Output Enable
(G) must be low in order to read the data from the
memory.
Read the Manufacturer Identifier
The manufacturer’s identifier can be read with two
methods: a Read operation or a Read instruction.
Read Operation.
The manufacturer’s identifier can
be read with a Read operation with specific logic
levels applied on A0, A1, A6 and the V
ID
level on
A9 (See Table 7).
Read Instruction.
The manufacturer’s identifier
can also be read with a single read operation
immediatly following the AS instruction (See Table
5A and Table 7).
Read the Flash Identifier
The Flash identifier can be read with two methods:
a Read operation or a Read instruction.
Read Operation.
The Flash identifier can be read
with a single Read operation with specific logic
levels applied on A0, A1, A6 and the V
ID
level on
A9 (See Table 7).
Read Instruction.
The Flash identifier can also be
read with a single read operation immediatly follow-
ing the AS instruction (See Table 5A and Table 7).
