Reply:
01 CF 06 00 ST CH CL CV CI C1 C2
where CF = 3 or 4
ST = status byte (for details see §6.6).
CH = tag code, high-order byte.
CL = tag code, low-order byte.
CV = counter for valid tag sightings.
CI = counter for invalid tag sightings.
CV and CI counters are reset when:
-
A new code is read twice (i.e. on VA and NC status bits rising edge).
-
The same tag disappears and appears again.

D7
D4 D3
D0
type
version
major revision
minor revision
where type identifies the equipment. Only one value is currently defined:
11 (0xBH) – MOL1312
The other 3 nibbles define the version number coded in BCD, e.g. 012H corresponds to 0.1.2
