Description
Current_1 - selects the current drive capability of the
TIMING_OUT_1 pin. Set this bit HIGH for high current
drive. Otherwise, the current drive will be low.
Reference:
This register is used to select one of the 10
pre-programmed or 4 user programmed timing signals
available for output on the TIMING_OUT_1 pin. See
Table 3-11
Note: The default setting of this register is 0001b, which
corresponds to H Sync.
Reference:
