544 / 904 page  Section 14 Timer Unit (TMU) Rev.1.50 Aug. 30, 2006 Page 504 of 860 REJ09B0288-0150 14.4.3 Interrupt Sources and Priorities The TMU generates 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 interrupt event register (INTEVT2) for these interrupts and interrupt processing occurs according to the codes. The relative priorities of channels can be changed using the interrupt controller (see section 4, Exception Handling, and section 8, Interrupt Controller (INTC)). Table 14.1 lists TMU interrupt sources. Table 14.1 TMU Interrupt Sources Channel Interrupt Source Description Priority 0 TUNI0 Underflow interrupt 0 High 1 TUNI1 Underflow interrupt 1 2 TUNI2 Underflow interrupt 2 Low 14.5 Usage Notes 14.5.1 Writing to Registers Synchronization processing is not performed for timer counting during register writes. When writing to registers, always clear the appropriate start bits for the channel (STR2 to STR0) in TSTR to halt timer counting. 14.5.2 Reading Registers Synchronization processing is performed for timer counting during register reads. When timer counting and register read processing are performed simultaneously, the register value before TCNT counting down (with synchronization processing) is read. |
