Interrupts
Tables 1.16 and 1.17 show the interrupt sources and vector addresses. When an interrupt is received, the
program is executed from the address shown by the respective interrupt vector.
The vector addresses for the interrupts in Table 1.16 are fixed (interrupt vector addresses). These inter-
rupts are not affected by the interrupt enable flag (I flag) (non-maskable interrupts).
The vector table addresses for the interrupt in Table 1.17 are variable, being determined as relative to the
fixed address in the interrupt table register (INTB) (variable interrupt addresses). These interrupts can be
enabled or disabled using the interrupt enable flag (I flag) (maskable interrupts). 64 vectors can be set in
the interrupt table register (INTB). Any software interrupt Nos. 0 to 63 can be assigned to each vector. By
using the INT instruction to specify a software interrupt No., the program can be executed starting at the
address indicated by the respective vector. The BRK instruction interrupt has interrupt vectors in both the
fixed vector addresses and variable vector addresses. When the contents of FFFE416 to FFFE716 are all
“FF16”, the program is executed from the address shown in the BRK instruction interrupt vector in the
variable vector addresses.
Specify the starting address of the interrupt program in the interrupt vector. Figure 1.25 shows the format
for specifying the address.
