Chapter 4 — BRI Commands

Basic Reader Interface Programmer Reference Manual
WRITE EMM_SENDSPI
Purpose:
This command provides the interface to support SPI master operation of the
EM4325 chip. It allows the reader to send SPI commands to an SPI slave device
attached to the EM4325. The EMM_SENDSPI is a data field that can be used in a
WRITE command.
Syntax:
WRITE [flex_query_selector] EMM_SENDSPI(<SPI_response_size>,
<SPI SCLK>, <SPI initial delay>, <SPI byte delay>)= H<Data>
[TAGTYPE=<tagtype list>] [WHERE <data condition>]
[PASSWORD=<"access_password">]
<SPI_response_size>, <SPI SCLK>, <SPI initial delay>, <SPI byte delay> = Numeric
values corresponding directly to the parameters in the SPI packet portion of the
command packet.
Examples:
Example 1:
WRITE EMM_SENDSPI(0,0,0,0)=H1234
H300833B2DDD901400000000000000000 WOK
Example 2:
WRITE EMM_SENDSPI(2,0,0,0)=H1234
H300833B2DDD901400000000000000000 H5678
WRITE EMM_RESETALARMS
Purpose:
This command allows a reader to reset the tag alarm conditions for Aux, Under
Temp, and Over Temp. The EMM_RESETALARMS is a data field that can be used
in a WRITE command.
Syntax:
WRITE [flex_query_selector] EMM_RESETALARMS [TAGTYPE=<tagtype
list>] [WHERE <data condition>] [PASSWORD=<"access_password">]
Example:
WRITE EMM_RESETALARMS
H300833B2DDD901400000000000000000 WROK
Generic Tag Access Command
The generic tag access command can be used to invoke any vendor custom
EPCC1G2 command that meets the following guidelines:
•
The command is valid in the open or secured state.
•
The command is formatted as follows:
