5.1.5Video Port Pin Data Input Register (PDIN)

The read-only video port pin data input register (PDIN) is shown in Figure 5–5 and described in Table 5–6. PDIN reflects the state of the video port pins. When read, PDIN returns the value from the pin’s input buffer (with appropriate synchronization) regardless of the state of the corresponding PFUNC or PDIR bit.
