10.5.3
The ITU has compare match/input capture A interrupts, compare match/input capture B interrupts
and overflow interrupts for each channel. Each of the fifteen of these three types of interrupts are
allocated their own independently vectored addresses. When the interrupt’s interrupt request flag
is set to 1 and the interrupt enable bit is set to 1, the interrupt is requested.
The channel priority order can be changed with the interrupt controller. For more information, see
section 5, Interrupt Controller. The compare match/input capture A interrupts of channels 0–3 can
start the DMAC to transfer data. Table 10.17 lists the interrupt sources.
