Field : Interrupt Mask Field - gpio_intmask | ||||||||||
Controls whether an interrupt on Port A Data Register can generate an interrupt to the interrupt controller by not masking it. The unmasked status can be read as well as the resultant status after masking. Field Enumeration Values:

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.
