Write Mode — This control bit defines the write mode of this register.
0 Write to all fields in this register on write access.
1 Write to SEL field only on write access.
14–8
SEL
Strobe Signal Select — This control field selects one of the strobe signals given in Tabl e 3 -1 2 to be enabled or
disabled and assigned to one of the four strobe ports given in Table 3- 12.
4
ENB
Strobe Signal Enable — The control bit is used to enable and to disable the strobe signal selected by
STBSSEL.
0 Strobe signal is disabled and not assigned to any strobe port.
1 Strobe signal is enabled and assigned to the strobe port selected by STBPSEL.
1–0
STBPSEL
Strobe Port Select — This field selects the strobe port that the strobe signal selected by the SEL is assigned
to. All strobe signals that are enabled and assigned to the same strobe port are combined with a binary OR
operation.
00 assign selected signal to DBG0
01 assign selected signal to DBG1
10 assign selected signal to DBG2
11 assign selected signal to DBG3
