11.4.2
The status flag can be cleared by writing a 0 from the CPU. Figure 11.9 shows the timing.
11.4.3
The TMU produces underflow interrupts for each channel. When the interrupt request flag and
interrupt enable bit are both set to 1, the interrupt is requested. Codes are set in the exception
source register (INTEVT) 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 6,
Interrupt Controller) and section 4, Exception Handling. Table 11.3 lists TMU interrupt sources.
