Important: This register is only writable if the Layer 1 state machine of the SBCX-X is
disabled (TR_CONF0.L1SW = 1)! With the SBCX-X layer 1 state machine enabled, the
signals from this register are automatically generated, but nevertheless this register can
always be read.
DPRIO can also be written in intelligent NT mode.
