Video Port Pin Data Clear Register (PDCLR)
The video port pin data clear register (PDCLR) is shown in Figure 5–8 and
described in Table 5–9. PDCLR 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 low. Writing a 1 to a bit of PDCLR clears the corresponding bit in
PDOUT. Writing a 0 has no effect. Register reads return all 0s.
