Bits Name Description
31–0 INT_MASK Interrupt mask. Each bit corresponds to an interrupt source. The corresponding IMRHn bit
determines whether an interrupt condition can generate an interrupt. The corresponding
IPRHn bit reflects the state of the interrupt signal even if the corresponding IMRHn bit is
set.
0 The corresponding interrupt source is not masked
1 The corresponding interrupt source is masked
