SL RC400

Preliminary

PRODUCT SERIAL NUMBER

The SL RC400 holds a four byte serial number that is unique for each device.

INTERNAL:

These 2 bytes hold internal trimming parameters.

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

GsConfCW Register (see chapter 13.2.1). 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 Rsref,max,n and is measured with GsConfCW

CRC

The content of the product information field is secured via a CRC-byte, which is checked during start up.

6.3

Initialising Phase (see 11.3), using the Start Up Register Initialisation File.

Furthermore, the user may initialise the SL RC400 registers with values from the Register Initialisation File

executing the LoadConfig-Command (see 16.6.1).

Notes:

•

The Page-Register (addressed with 10hex, 18hex, 20hex, 28hex) is skipped and not initialised.

•

Make sure that all PreSet registers are not changed.

•

Make sure, that all register bits that are reserved for future use (RFU) are set to 0.

6.3.1

START UP REGISTER INITIALISATION FILE (READ/WRITE)

The content of the E²PROM memory block address 1 and 2 are used to initialise the SL RC400 registers

10hex to 2Fhex during the Initialising Phase automatically. The default values written into the E²PROM during

production are shown in chapter 6.3.2.

The assignment is the following:
