Table 9. GPIO Set Data Register (SET_DATA n) Field Descriptions

Bit Field Value Description

31-16 SET n Set output drive state of GPIO pin n. The SET n bit is used to set the output of pin n on GPIO bank 2 I + 1

only when pin n is configured as an output (DIR n = 0). The SET n bit is ignored when GPIO pin n is

configured as an input. Writing a 1 to the SET n bit sets the output drive state of the corresponding GPIO

pin n; reading the SET n bit returns the output drive state of the corresponding GPIO pin n. This bit field

configures the GPIO pins on GPIO banks 1 and 3.

0 No effect.

1 Set GPIO pin n output to 1.

15-0 SET n Set output drive state of GPIO pin n. The SET n bit is used to set the output of pin n on GPIO bank 2 I only

when pin n is configured as an output (DIR n = 0). The SET n bit is ignored when GPIO pin n is configured

as an input. Writing a 1 to the SET n bit sets the output drive state of the corresponding GPIO pin n;

reading the SET n bit returns the output drive state of the corresponding GPIO pin n. This bit field

configures the GPIO pins on GPIO banks 0, 2, and 4.

0 No effect.

1 Set GPIO pin n output to 1.
