is transferred in the upper half of the address bus. In all register indirect
input output instructions, including block I/O transfers, the content of
register C is transferred to the lower half of the address bus (device
address) while the content of register B is transferred to the upper half of
the address bus.
CPU Control Group
Table 20 illustrates the six general-purpose CPU control instructions. The
NOP
operation until a subsequent interrupt is received, while the
used to lock out and enable interrupts. The three interrupt mode
commands set the CPU to any of the three available interrupt response
modes as follows. If Mode 0 is set, the interrupting device can insert any
instruction on the data bus and allow the CPU to execute it. Mode 1 is a
simplified mode where the CPU automatically executes a restart (
location
content is pushed onto the stack). Mode 2 is the most powerful because it
allows for an indirect call to any location in memory. With this mode, the
CPU forms a 16-bit memory address where the upper eight bits are the
content of register I and the lower eight bits are supplied by the
interrupting device. This address points to the first of two sequential bytes
in a table where the address of the service routine is located. The CPU
automatically obtains the starting address and performs a
instruction to this address.
