5.1.7 Video Port Pin Data Set Register (PDSET)

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 5-7and described in Table 5-8.

Table 5-8. Video Port Pin Data Set Register (PDSET) Field Descriptions

Bit	field (1)	symval (1)	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
		VDATAnHI	1	Sets PDOUT[n] (VDATA[n]) bit to 1.
