Field : Port A Data - gpio_swporta_dr | |
Values written to this register are output on the I/O signals of the GPIO Data Register, if the corresponding data direction bits for GPIO Data Direction Field are set to Output mode. The value read back is equal to the last value written to this register. Check the GPIO chapter in the handbook for details on how GPIO2 is implemented. Field Access Macros: | |

WARNING: The C register and register group struct declarations are provided for convenience and illustrative purposes. They should, however, be used with caution as the C language standard provides no guarantees about the alignment or atomicity of device memory accesses. The recommended practice for writing hardware drivers is to use the SoCAL access macros and alt_read_word() and alt_write_word() functions.
