Port [A/B/C/D/E] Data Output Write Mask
These bits are used to protect the corresponding register of GPIOx_DOUT bit[n] .
When set the DMASK bit[n] to 1, the corresponding GPIOx_DOUTn bit is protected.
The write signal is masked, write data to the protect bit is ignored
1 = The corresponding GPIOx_DOUT[n] bit is protected
0 = The corresponding GPIOx_DOUT[n] bit can be updated
