Individual bits to control the state of pins configured as GPIO output.
bit 24 controls GPIO_PSC2_3 (PSC2_3 pin)
bit 25 controls GPIO_PSC2_2 (PSC2_2 pin)
bit 26 controls GPIO_PSC2_1 (PSC2_1 pin)
bit 27 controls GPIO_PSC2_0 (PSC2_0 pin)
0 = Drive 0 on the pin (default)
1 = Drive 1 on the pin
Individual bits to control the state of pins configured as GPIO output.
