Section 17 32K Timer (TM32K)
17.4
At the interrupt interval, the 32K timer generates a 32K timer-overflow interrupt (32KOVI) that
lasts for three cycles of the subclock. Since 32KOVI is internally connected to IRQ15, the IRQ15F
bit is set to 1 when an interrupt is generated. For the IRQ15 setting, select an interrupt request
generated at the falling edge with ISCR. For details, see section 7, Interrupt Controller.
The 32K timer operates in both software-standby and deep-software standby modes. Through
generation of the 32K timer interrupt, the timer can provide the trigger for release from software
standby and deep-software-standby modes. For details, see section 28, Power-Down Modes.
