74 00000008 ; Description : Disable/Enable interrupts by preserving
the state of interrupts. Generally speaking, the
75 00000008 ; state of the interrupt disable flag is s
tored in the local variable 'cpu_sr' & interrupts
76 00000008 ; are then disabled ('cpu_sr' is allocated
in all functions that need to disable interrupts).
77 00000008 ; The previous interrupt state is restored
by copying 'cpu_sr' into the CPU's status register.
