5.1.7 Video Port Pin Data Set Register (PDSET)
GPIO Registers
PDSET is an alias of the video port pin data output register (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.
The video port pin data set register (PDSET) is shown in Figure 5-7 and described in Table 5-8 .

Value Description
31-23 Reserved - 0 Reserved. The reserved bit location is always read as 0. A value written to this field
has no effect.
22 PDSET22 OF( value) Allows PDOUT22 bit to be set to a logic high without affecting other I/O pins controlled
by the same port.
DEFAULT 0 No effect.
NONE
VCTL3HI 1 Sets PDOUT22 (VCTL3) bit to 1.
21 PDSET21 OF( value) Allows PDOUT21 bit to be set to a logic high without affecting other I/O pins controlled
by the same port.
DEFAULT 0 No effect.
NONE
VCTL2HI 1 Sets PDOUT21 (VCTL2) bit to 1.
20 PDSET20 OF( value) Allows PDOUT20 bit to be set to a logic high without affecting other I/O pins controlled
by the same port.
DEFAULT 0 No effect.
NONE
VCTL1HI 1 Sets PDOUT20 (VCTL1) bit to 1.
19-2 PDSET[19-2] OF( value) Allows PDOUT[19-2] bit to be set to a logic high without affecting other I/O pins
controlled by the same port.
DEFAULT 0 No effect.
NONE
VDATA nHI 1 Sets PDOUT[ n] (VDATA[ n]) bit to 1.
