6.3.9 Version
The VERSION register contains the release version of the DSL Master IP Core. The regis‐
ter is write protected.

6.3.10 Release Date
The RELEASE register contains the release date of the DSL Master IP Core. The release
date value can be read by sequential access to a three byte structure with arbitration
rules to avoid possible conflicts between both interfaces "drive" and "safe 1" where the
value can be accessed. To read the release date value the following steps are required:
•
During one host interface transaction the VERSION register (see 5.3.9) is read
first; this enables access to the release date register.
•
The first returned byte from the release date register encodes the release year as
binary number in excess of 2000 (10h = 2016, ... 63h = 2099).
•
The second returned byte from the release date register encodes the release
month as binary number (01h = January, ... 0Ch = December).
•
The third returned byte from the release date register encodes the release day as
binary number (01h = 1st, ... 1Fh = 31st).
Every reading to the RELEASE register after the third byte repeats the third returned
byte. To reset the RELEASE register a new reading of the VERSION register is required.
While one of the interfaces accesses the RELEASE register ("drive" or "safe 1") the other
returns 00h. When using the Basic Interface (see chapter 9.4) the access right to the
RELEASE register is released when the freeze signal ("hostx_f") is lowered.
NOTE
Access from Safe 2 Interface is not possible.
6.3.11 Encoder ID
The ENC_ID registers contain the designation code of the motor feedback system con‐
nected to the DSL Master. In the current protocol specification, the designation code is
20 bits long. With later enhancements, the free bits in the encoder ID registers are
used to indicate special characters.
These registers are write protected.
