Appendix B: Register Details
Register Intrpt_mask_reg0 Details
Each bit in this register corresponds to a bit in the interrupt status register. If bit i in the interrupt mask
register is set, the corresponding bit in the interrupt status register is ignored. Otherwise, an interrupt is
generated whenever bit i in the interrupt status register is set.
Bits in this register are set through a write to the interrupt disable register and are cleared through a write
to the interrupt enable register.
All mask bits are set and all interrupts are disabled after reset.
Interrupt mask register has the same format as the interrupt status register.
