Section 15 Timer (TMU)
15.4.2
The status flag is cleared when 0 is written by the CPU. Figure 15.7 shows the timing.
15.4.3
The TMU generates underflow interrupts for each channel. When the interrupt request flag and
interrupt enable bit are both set to 1, the corresponding interrupt is requested. When an interrupt is
generated, codes are set in the interrupt event register (INTEVT, INTEVT2). Provide the
appropriate interrupt handling according to the codes.
The channel priority can be changed using the interrupt controller (see section 4, Exception
Handling, and section 7, Interrupt Controller (INTC)). Table 15.2 lists TMU interrupt sources.
