14.3
Each interrupt source can be either high priority or low
priority. If both priorities are requested simultaneously, the
processor will branch to the high priority vector. If there are
simultaneous requests from sources of the same priority,
then interrupts will be serviced in the following order:
X0, S1, ADC, T0, CT0, CM0, X1, CT1, CM1, T1, CT2,
CM2, S0, CT3, T2.
A low priority interrupt routine can only be interrupted by a
high priority interrupt. A high priority interrupt routine can
not be interrupted.
15 POWER REDUCTION MODES
The P8xC592 has three software-selectable modes to
reduce power consumption. These are:
Sleep mode, affecting the CAN-controller only
Idle mode, affecting the
– CPU (halted)
– Timer 2 (stopped and reset)
– PWM0, PWM1 (reset, output = HIGH)
– ADC (aborted if in progress)
Power-down mode, affecting the whole P8xC592
device.
