Table 4-39. GPIO Port C Set (GPCSET) Register Field Descriptions
Bits Field Value Description
31-24 Reserved Reserved
23-0 GPIO87-GPIO64 Each GPIO port C pin (GPIO64-GPIO87) corresponds to one bit in this register as shown in
Figure 4-31 .
0 Writes of 0 are ignored. This register always reads back a 0.
1 Writing a 1 forces the respective output data latch to high. If the pin is configured as a GPIO
output then it will be driven high. If the pin is not configured as a GPIO output then the latch is
set but the pin is not driven.
Table 4-40. GPIO Port C Clear (GPCCLEAR) Register Field Descriptions
Bits Field Value Description
31-24 Reserved Reserved
23-0 GPIO87-GPIO64 Each GPIO port C pin (GPIO64-GPIO87) corresponds to one bit in this register as shown in
Figure 4-31 .
0 Writes of 0 are ignored. This register always reads back a 0.
1 Writing a 1 forces the respective output data latch to low. If the pin is configured as a GPIO
output then it will be driven low. If the pin is not configured as a GPIO output then the latch is
cleared but the pin is not driven.
Table 4-41. GPIO Port C Toggle (GPCTOGGLE) Register Field Descriptions
Bits Field Value Description
31-24 Reserved Reserved
23-0 GPIO87-GPIO64 Each GPIO port C pin (GPIO64-GPIO87) corresponds to one bit in this register as shown in
Figure 4-31 .
0 Writes of 0 are ignored. This register always reads back a 0.
1 Writing a 1 forces the respective output data latch to toggle from its current state. If the pin is
configured as a GPIO output then it will be driven in the opposite direction of its current state. If
the pin is not configured as a GPIO output then the latch is cleared but the pin is not driven.
