13.4.2
The status flag can be cleared by writing 0 from the CPU. Figure 13.9 shows the timing.
13.4.3
The TMU produces underflow interrupts for each channel. When the interrupt request flag and
interrupt enable bit are both set to 1, an interrupt is requested. Codes are set in the interrupt event
registers (INTEVT, INTEVT2) for these interrupts and interrupt handling occurs according to the
codes.
The relative priorities of channels can be changed using the interrupt controller (see section 4,
Exception Handling, and section 7, Interrupt Controller (INTC)). Table 13.3 lists TMU interrupt
sources.
