The 32K timer (TM32K) is a 24-bit timer. Either 8- or 24- counter operation is selectable. It
generates a 32K timer interrupt every time the interrupt period of the counter elapses. Figure 17.1
shows a block diagram of the TM32K.
17.1
• A 32K timer interrupt (32KOVI) is generated at the overflow interval for the counter.
• Eight interrupt overflow cycles of 250 ms, 500 ms, 1 s, 2 s, 30 s, 60 s, approx. 22.7 days, and
• Counter operational except in hardware standby mode or the reset state.
• Canceling software standby mode and deep software standby mode is possible.
approx. 45.5 days settable.
