Table 1-74. GPIO Port B Set (GPBSET) Register Field Descriptions
Bits Field Value Description
31-0 GPIO63-GPIO32 Each GPIO port B pin (GPIO32-GPIO63) corresponds to one bit in this register as shown in
Figure 1-69.
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 1-75. GPIO Port B Clear (GPBCLEAR) Register Field Descriptions
Bits Field Value Description
31-0 GPIO63-GPIO32 Each GPIO port B pin (GPIO32-GPIO63) corresponds to one bit in this register as shown in
Figure 1-69.
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 1-76. GPIO Port B Toggle (GPBTOGGLE) Register Field Descriptions
Bits Field Value Description
31-0 GPIO63-GPIO32 Each GPIO port B pin (GPIO32-GPIO63) corresponds to one bit in this register as shown in
Figure 1-69.
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.
