The first-level GP_INT interrupt comprises several second-level interrupts for the 13 GPIO pins. Each
of these has a status bit in Register R30 and a mask bit in Register R35, as defined in Table 147.

Interrupt mask.
0 = Do not mask interrupt.
1 = Mask interrupt.
Each bit in R38 enables or masks the
corresponding bit in R30. The default
value for these bits is 0 (unmasked).
