The command PSsets the password, which the R/W head communicates to the
data carrier in password mode.
Operating mode "Default Read"
In "default read" operating mode, 1 or 2 words are read extremely quickly. The
area of memory earmarked for reading is already specified on the tag. The R/W
head does not have to identify the memory area for the tag.
The start and end of the read range are stored in the bytes 0 and 1 of the control
word. As soon as power is supplied to the tag, it sends data from the data range
defined by the start and end of the read range. The data range between read
range start and end is read with the read commands SR (Single read words) and
ER (enhanced buffered read words) when <WordAddr> is set to 0000h and
<WordNum> to 00h.
