| ) |
Initialize a complete port of pins from a single init structure.
The configuration structure used in this function has a 1:1 mapping to the GPIO and HSIOM registers. Refer to the device Technical Reference Manual (TRM) for the register details on how to populate them.
| base | Pointer to the pin's port register base address |
| config | Pointer to the pin config structure base address |

| uint32_t | outVal, | ||
| en_hsiom_sel_t | hsiom | ||
| ) |
Initialize the most common configuration settings for all pin types.
These include, drive mode, initial output value, and HSIOM connection.
| base | Pointer to the pin's port register base address |
| pinNum | Position of the pin bit-field within the port register |
| driveMode | Pin drive mode. Options are detailed in Pin drive mode macros |
| outVal | Logic state of the output buffer driven to the pin (1 or 0) |
| hsiom | HSIOM input selection |
| void Cy_GPIO_Port_Deinit | ( | GPIO_PRT_Type * | base | ) |

| uint32_t | pinNum, | ||
| en_hsiom_sel_t | value | ||
| ) |
Configures the HSIOM connection to the pin.
Connects the specified High-Speed Input Output Multiplexer (HSIOM) selection to the pin.
| base | Pointer to the pin's port register base address |
| pinNum | Position of the pin bit-field within the port register |

| __STATIC_INLINE GPIO_PRT_Type * Cy_GPIO_PortToAddr | ( | uint32_t | portNum | ) |
Retrieves the port address based on the given port number.
This is a helper function to calculate the port base address when given a port number. It is to be used when pin access needs to be calculated at runtime.
| portNum | Port number |
