Interrupt mask. Each bit corresponds to an interrupt source defined by the EIR register. The
corresponding EIMR bit determines whether an interrupt condition can generate an interrupt. At
every clock, the EIR samples the signal generated by the interrupting source. The corresponding
EIR bit reflects the state of the interrupt signal even if the corresponding EIMR bit is set.
0 The corresponding interrupt source is masked .
1 The corresponding interrupt source is not masked.
Reserved, should be cleared.
