*) if a bit is set to 1, and the corresponding bit of GSEL_A is 0, GPIO pin is used by the other
dedicated function blocks.

GPIO_A[11,8,7,4,3,0] Function Select
0
GPIO_A[11,8,7,4,3,0] pin is working as Normal GPIO Function
1
GPIO_A[11,8,7,4,3,0] is the output of 6 timer/counter
*) this bit field is only valid only if the corresponding bit of GSEL_A is set to 0

*) if a bit is set to 1, the corresponding GPIO pin is set to output mode.
The GPIO_B[29:28] and GPIO_B[27:26] pin is unable to be set to different I/O mode. That is,
GPIO_B[29] have always same direction with GPIO_B[28], and it is same as GPIO_B[27] and
GPIO_B[26], so to make GPIO_B[27:26] output port, you must set both GIOCON_B[27] and
GIOCON_B[26] to 1.

*) if a bit is set to 1, and the corresponding GPIO pin is set to output mode, the output of internal
peripherals occupy the corresponding GPIO pin.
