GPIO PORT
GPIO_C Data Register (GDATA_C)

Data for GPIO_C[15:0] pin
* This register is valid only in TCC761.
If a certain GPIO_C pin is set to output mode and act as GPIO, the corresponding bit of
this register controls the status of GPIO_C pin; Low or High. If it is set to input mode and
act as GPIO, the corresponding bit represents the status of GPIO_C pin; Low or High.
GPIO_C Direction Control Register (GIOCON_C)
0x80000324

Direction control for GPIO_C[15:0] pin
* This register is valid only in TCC761.
If a bit is set to 1, the corresponding GPIO pin is set to output mode. GPIO_C port works
only in 16-bit bus mode. In 32-bit bus mode, this port works as an upper half bus of 32-bit
data bus.
GPIO_D Data Register (GDATA_D)
0x80000330

Data for GPIO_D[21:16]
15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
Data for GPIO_D[15:0] pins (Bits [14:0] are valid only in TCC761)
GPIO_D Direction Control Register (GIOCON_D)
0x80000334
31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16

Direction Control for GPIO_D[21:16]
15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
Direction control for GPIO_D[15:0] pin (Bits [14:0] are valid only in TCC761)
* At power on reset, internal pull-up resistors are enabled for GPIO_D[21:18] pins.
If a bit is set to 1, the corresponding GPIO_D pin is set to output mode. If set to 0, GPIO_D pin is set to input
mode.
