3.3.3 Interrupt Controller
Figure 3.3 (9) shows an abbreviated interrupt circuit diagram.
The left half of this diagram shows the interrupt controller and
the right half shows the CPU interrupt request signal circuit
and hold release circuit.
The interrupt controller has an interrupt request flipflop
and interrupt enable/disable flag for each interrupt channel
(total: 18 channels), and a micro DMA enable/disable flag. The
interrupt request flip-flop latches interrupt requests that arrive
from the periphery. This flipflop is reset to “0” when there is a
reset, when the CPU receives an interrupt and reads the vector
of that interrupt channel, and when an instruction that clears
the interrupt request (writes “vector value/8” to memory
address FFE0H) for that channel is executed.
LD (0FFE0H), 60H/8
For example, when LD (0FFE0H), 38H/8 is executed, the
interrupt request flipflop for the interrupt channel [INTT1] with
the vector value 38H is reset to “0” (to clear the flipflop, also
write to address FFC9H when the interrupt request flag is
assigned to FFE1H and FFE2H).
Table 3.3 (5) shows the “interrupt vector value/8” values.
The status of the interrupt request flipflop can be determined
by reading memory address FFC9H, FFCAH or FFCBH. “0”
means no interrupt request and “1” means an interrupt
request. Figure 3.3 (8) shows the bit layout when the interrupt
request flipflop is read.
