The AT83C5134/35/36 has a total of 11 interrupt vectors: two external interrupts (INT0 and
INT1), three timer interrupts (timers 0, 1 and 2), the serial port interrupt, SPI interrupt, Keyboard
interrupt, USB interrupt and the PCA global interrupt. These interrupts are shown in Figure 16-1.
Each of the interrupt sources can be individually enabled or disabled by setting or clearing a bit
in the Interrupt Enable register
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 (Table 16-3.) and in the Interrupt Priority
