Description:
The Microchip Technology Inc. 11AAXXX/11LCXXX
(11XX*) devices are a family of 1 Kbit through 16 Kbit
Serial Electrically Erasable PROMs. The devices are
organized in blocks of x8-bit memory and support the
patented** single I/O UNI/O® serial bus. By using
Manchester encoding techniques, the clock and data
are combined into a single, serial bit stream (SCIO),
where the clock signal is extracted by the receiver to
correctly decode the timing and value of each bit.
Low-voltage design permits operation down to 1.8V (for
11AAXXX devices), with standby and active currents of
only 1 uA and 1 mA, respectively.
The 11XX family is available in standard packages
including 8-lead PDIP and SOIC, and advanced pack-
aging including 3-lead SOT-23, 3-lead TO-92, 4-lead
Chip Scale, 8-lead TDFN, and 8-lead MSOP.

11XX
4.2 Current Address Read (CRRD)
Instruction
The internal address counter featured on the 11XX
maintains the address of the last memory array loca-
tion accessed. The CRRD instruction allows the mas-
ter to read data back beginning from this current
location. Consequently, no word address is provided
upon issuing this command.
Note that, except for the initial word address, the
READ and CRRD instructions are identical, including
the ability to continue requesting data through the use
of MAKs in order to sequentially read from the array.
As with the READ instruction, the CRRD instruction is
terminated by transmitting a NoMAK.
Table 4-2 lists the events upon which the internal
address counter is modified.

Note: If, following each data byte in a READ,
WRITE, or CRRD instruction, neither a
MAK nor a NoMAK edge is received
(i.e., if a standby pulse occurs instead),
the internal address counter will not be
incremented.

Note: During a Write command, once the last
data byte for a page has been loaded,
the internal Address Pointer will rollover
to the beginning of the selected page.
