WebJan 9, 2024 · Three types of interrupts are defined: software interrupts, clock interrupts, and external interrupts. User-state software interrupts are triggered by setting the software interrupt wait bit (USIP) of uip of the current hardware thread. Clearing this bit clears the pending software interrupt. When the USIE in uie is zero, user-state software ... WebAug 5, 2024 · The intention is to. allocate the bits of sstateen CSRs starting at the least-significant. end, bit 0, through to bit 31, and then on to the next-higher-numbered. sstateen CSR. For every bit with a defined purpose in an sstateen CSR, the same bit. is defined in the matching mstateen CSR to control access below machine.
