AS39513 − Detailed Description

For direct commands that do not have a response, the signals

are as illustrated below.

Figure 53:

Direct Commands Without Response

When a direct command has a response, the signaling is similar

to the Read command, as shown below.

3’b110

Do Measurement

Duplicates the functionality of the RFID Do Measurement command. (See

that command for more details.) Before sending this Direct command it is

necessary to send a Reset Direct command via SPI. The DOMEAS[1:0]

parameter for the Do Measurement command is taken from DPARAM[1:0].

The response is the same 16-bit format as the RFID Do Measurement

command, unless there is an ADC error. In the case of an ADC error, 16’hA300

is returned. Note if TV2SET<TV1SET-1 which is not a valid configuration, a Do

Measurement command via SPI will result in 0x0000 being read; the ADC

error code 0xA300 is not returned in this particular case.

3’b111

Get Log Status

Duplicates the functionality of the RFID Get Log Status command. (See that

command for more details.) The response is the same 8-bit format as the RFID

Get Log Status command.
