2.1.4 DC_REG Register
DC_REG is used to monitor and control the daughter card interface. DC_DET detects
the presence of a daughter card. DC_STAT and DC_CNTL provide simple
communications with the daughter card through readable status lines and writable
control lines.
The daughter card is released from reset when the DSP is released from reset.
DC_RST can be used to put the card back in reset.
2.1.5 VERSION Register
The VERSION register contains two read only fields that indicate the BOARD and
CPLD versions. This register will allow your software to differentiate between
production releases of the DSK and account for any variances. This register is not
expected to change often, if at all.
