The existing control and status register definitions support RISC-V's error and memory exceptions, and a small number of interrupts.
12.
The number of registered inhabitants in the town s personal status register is estimated at 800 people belonging to the Catholique and Maronite community.
13.
If the interrupt handler does not modify the saved status register, returning from the interrupt will then resume the original low-power mode.
14.
Another alternative to the status register is for processor instructions to deposit status information in a general-purpose register when the program requests it.
15.
The status register contains various mode bits, but the processor does " not " have the standard ALU result flags like overflow.
16.
CALL and GOTO instructions specify the low 9 bits of the new code location; additional high-order bits are taken from the status register.
17.
A status register may often have other fields as well, such as more specialized flags, interrupt enable bits, and similar types of information.
18.
In many designs, the ALU also exchanges additional information with a status register, which relates to the result of the current or previous operations.
19.
The status register contains 4 arithmetic status bits, a global interrupt enable, and 4 bits that disable various clocks to enter low-power mode.
20.
Microprocessors typically have a status register that is composed of such flags, used to indicate various post-operation conditions, for example an arithmetic overflow.
