7.4.3 Interrupt Clear Register (IntClear - 0xFFE0 0FE8)
7.4.4 Interrupt Set Register (IntSet - 0xFFE0 0FEC)
Table 229. Interrupt Enable register (intEnable - address 0xFFE0 0FE4) bit description
The Interrupt Clear register (IntClear) is a Write Only register with an address of
0xFFE0 0FE8. The interrupt clear register bit definition is shown in
Table 230. Interrupt Clear register (IntClear - address 0xFFE0 0FE8) bit description
The interrupt clear register is write-only. Writing a 1 to a bit of the IntClear register clears
the corresponding bit in the status register. Writing a 0 will not affect the interrupt status.
The Interrupt Set register (IntSet) is a Write Only register with an address of
0xFFE0 0FEC. The interrupt set register bit definition is shown in
