The interrupt level control register 3 is a special function register (SFR) used to set the level of the interrupt
source enabled by IE3.
Write access to this register is possible only when the interrupt level control is enabled by the ILEN register.
Level 1 to 4 can be set for each interrupt source. The register which has the higher level is given the higher
priority.
