10. Interrupt System
The TS80C31X2 has a total of 5 interrupt vectors: two external interrupts (INT0 and INT1), two
timer interrupts (timers 0 and 1) and the serial port interrupt. These interrupts are shown in Fig-
Figure 10-1. Interrupt Control System
Each of the interrupt sources can be individually enabled or disabled by setting or clearing a bit
in the Interrupt Enable register (See Table 10-2.Table 10-3.). This register also contains a global
disable bit, which must be cleared to disable all interrupts at once.
Each interrupt source can also be individually programmed to one out of four priority levels by
setting or clearing a bit in the Interrupt Priority register (See Table 10-3.) and in the Interrupt Pri-
ority High register (See Table 10-4.). shows the bit values and priority levels associated with
each combination.
