85 / 196 page  85/196 16-BIT TIMER (Cont’d) 10.4.4 Low Power Modes 10.4.5 Interrupts Note: The 16-bit Timer interrupt events are connected to the same interrupt vector (see Interrupts chap- ter). These events generate an interrupt if the corresponding Enable Control Bit is set and the interrupt mask in the CC register is reset (RIM instruction). 10.4.6 Summary of Timer Modes 1) See note 4 in Section 10.4.3.5 One Pulse Mode 2) See note 5 in Section 10.4.3.5 One Pulse Mode 3) See note 4 in Section 10.4.3.6 Pulse Width Modulation Mode Mode Description WAIT No effect on 16-bit Timer. Timer interrupts cause the device to exit from WAIT mode. HALT 16-bit Timer registers are frozen. In HALT mode, the counter stops counting until Halt mode is exited. Counting resumes from the previous count when the MCU is woken up by an interrupt with “exit from HALT mode” capability or from the counter reset value when the MCU is woken up by a RESET. If an input capture event occurs on the ICAPi pin, the input capture detection circuitry is armed. Consequent- ly, when the MCU is woken up by an interrupt with “exit from HALT mode” capability, the ICFi bit is set, and the counter value present when exiting from HALT mode is captured into the ICiR register.
