Command parameters:
2 bytes: 1 byte page size, 1 byte page address. Page size byte indicates
the number of bytes that are considered a page. Typical page sizes are
32 decimal for data memory, 8 for status memory, and 40 decimal for
Monetary iButtons. A page size of 0x00 indicates a 256-byte page. The
page address specifies the page number to be used for the first read
attempt.
EP2 data:
Length
9 bytes
8 bytes ROM ID of the 1-Wire device to be accessed
followed by the 1-Wire command code for “Extended
Read Memory”.
EP3 data:
Length
Description
If CH = 1 or page is not
redirected:
1 byte + page
size
Page number and contents of the page.
If CH = 0 and page is
redirected:
1 byte
Number of the page the addressed page is redirected
to.
Result Register:
Code
Condition
RDP, CRC,
NRS
ICP = 0, NTF = 0 or 1: and an error condition.
0x00
ICP = 0, NTF = 1: no error detected
None
ICP = 0, NTF = 0: no error detected
None
ICP = 1
SEARCH ACCESS—The SEARCH ACCESS command is used to either access a device using the
Search ROM command or to identify the devices on the active segments of a 1-Wire Network. Embedded
command bit SM is used to specify the type of search. Embedded command bit RTS is used to control
discrepancy information reporting. Additionally, embedded command bit F can be used to clear the
Communication command buffer and EP2/3 FIFOs if an error occurs during execution of the command.
An NRS error code indicates that there was no response on at least one of the 64 bits of the ROM search.
The EP2 FIFO must be pre-filled with ROM ID data before command execution. To prevent overflow,
the EP3 FIFO must be monitored (and read if necessary) during command execution if returning more
data than the size of the EP3 FIFO.
