The UTSTCREG register is used for factory testing only.
The UIPEND register is a read-only status register which reflects the state of the 32
interrupt levels. The state of the IRQ0 is shown in bit 0, the state of IRQ1 is shown in
bit 1 and so on. This register is accessible only in supervisor mode.

Stop enable.
0 = Enable system clock for IMB bus
1 = Disable IMB system clock
To avoid complications at restart and data corruption, system software must stop each slave on
the IMB before setting the STOP bit. Software must also ensure that all IMB interrupts have been
serviced before setting this bit.
Interrupt request multiplexing. These bits control the multiplexing of the 32 possible interrupt re-
quests onto the eight IMB interrupt request lines.
00 = Disables the multiplexing scheme on the interrupt controller within this interface. What this
01 = Enables the IMB IRQ control logic to perform a 2-to-1 multiplexing to allow transferring of
10 = Enables the IMB IRQ control logic to perform a 3-to-1 multiplexing to allow transferring of
11 = Enables the IMB IRQ control logic to perform a 4-to-1 multiplexing to allow transferring of
Half speed. The HSPEED bit controls the frequency at which the IMB3 runs with respect to the
U-bus. This is a modify-once bit. Software can write the reset value of this bit any number of
times. However, once logic 0 is written to this location, any attempt to rewrite this bit to a logic 1
will have no effect.
0 = IMB frequency is the same as that of the U-bus
1 = IMB frequency is one half that of the U-bus
