Video Port Pin Data Set Register (PDSET)
The video port pin data set register (PDSET) is shown in Figure 5–7 and
described in Table 5–8. PDSET is an alias of the video port pin data output reg-
ister (PDOUT) for writes only and provides an alternate means of driving GPIO
outputs high. Writing a 1 to a bit of PDSET sets the corresponding bit in
PDOUT. Writing a 0 has no effect. Register reads return all 0s.
