Table 6-3: Product Type Identification Definition
Byte 4 indicates the current version number.
PRODUCT SERIAL NUMBER:
The CL RC632 holds a four byte serial number that is unique for each device.
INTERNAL:
These 2 bytes hold internal trimming parameters.
RsMaxP:
Maximum Source Resistance for the p-Channel Driver Transistor of pin TX1 and TX2
The source resistance of the p-channel driver transistors of pin TX1 and TX2 may be adjusted via the value
GsCfgCW
in the
CWConductance Register
(see chapter 13.3). The mean value of the maximum adjustable
source resistance of the pins TX1 and TX2 is stored as an integer value in Ohms in byte RsMaxP.
This value is denoted as maximum adjustable source resistance Rs
ref,max,p
and is measured setting
GsCfgCW in the Register
CWConductance to 01
hex
. It is in the range between about 80 to 120 Ohm.
CRC:
The content of the product information field is secured via a CRC-byte, which is checked during start up.
