3.3.3 Interrupt Controller
Figure 3.3 (8) outlines the interrupt circuit. The left half of
this figure represents an interrupt controller, and the right side
comprises the CPU interrupt request signal circuit and HALT
release signal circuit.
The interrupt controller consists of Interrupt Request Flip-
flops, Interrupt Enable flags, and micro DMA enable flags
allocated to each of 14 channels. The Interrupt Request Flip-
flops serve to latch interrupt requests from peripherals. Each
flip-flop is reset to “0” when a reset or interrupt is acknowledged
by the CPU and the vector of the interrupt channel is read into
the CPU, or when the CPU executes an instruction that clears
an Interrupt Request Flip-flop for the specified channel (write
“vector divided by 8” in the memory address FFC3H). For
example, by executing.
LD (FF9EH), 58H/8,
The Interrupt Request Flip-flops for the interrupt channel
“INTT1” whose vector is 30H is reset to”0”. The status of an
Interrupt Request Flip-flops is found out by reading the memory
address FFC2H or FFC3H. “0” denotes there is not interrupt
request, and “1” denotes that an interrupt is request. Figure 3.3
(7) illustrates the bit configuration indicating the status of Interrupt
Request Flip-flops.
