7.6.13 Register 12 - Interrupt mask port 0 register
7.6.14 Register 13 - Interrupt mask port 1 register
All the bits of Interrupt mask port 0 register are set to logic 1 upon power-on or software
reset, thus disabling interrupts. Interrupts may be enabled by setting corresponding mask
bits to logic 0.
Table 16.
Legend: * default value.
