Fig. 5.2.4 Structure of timer Ai interrupt control register
5.2.4 Timer Ai interrupt control register
Figure 5.2.4 shows the structure of the timer Ai interrupt control register. For details about interrupts, refer
to “Chapter 4. INTERRUPTS.”
(1) Interrupt priority level select bits (bits 2 to 0)
(2) Interrupt request bit (bit 3)
b7
These bits select a timer Ai interrupt’s priority level. When using timer Ai interrupts, select priority
levels 1 to 7. When a timer Ai interrupt request occurs, its priority level is compared with the
processor interrupt priority level (IPL), so that the requested interrupt is enabled only when its priority
level is higher than the IPL. (However, this applies when the interrupt disable flag (I) = “0.”) To
disable timer Ai interrupts, set these bits to “000
This bit is set to “1” when the timer Ai interrupt request occurs. This bit is automatically cleared to
“0” when the timer Ai interrupt request is accepted. This bit can be set to “1” or “0” by software.
