3.2.6. GPIO_PIN_CFG
 Summary: Configures the gpio pins
 Command Stream
 Reply Stream
 Parameters:

GPIO0_PULL_CTL
0 = Disable pullup. Recommended setting if pin is driven.
1 = Enable pullup.

GPIO0_MODE[5:0]
0 = Do not modify the behavior of this pin.
1 = Input and output drivers disabled.
2 = CMOS output driven low.
3 = CMOS output driven high.
4 = CMOS input.
5 = 32 kHz clock.
6 = 30 MHz clock.
7 = Divided MCU clock.
8 = High when command complete, low otherwise.
9 = Low when command complete, high otherwise.
10 = High when command overlap occurs. TODO: What clears this.
