Individual Enable
The AT89C5130A/31A-M 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.
