CHAPTER 8 WATCHDOG TIMER

User’s Manual U18172EJ2V0UD

144

8.4.2 Watchdog timer operation when “low-speed internal oscillator can be stopped by software” is

selected by option byte

The operation clock of the watchdog timer can be selected as either the low-speed internal oscillation clock or

system clock.

After reset is released, operation is started at the maximum cycle of the low-speed internal oscillation clock (bits 2,

1, and 0 (WDCS2, WDCS1, WDCS0) of the watchdog timer mode register (WDTM) = 1, 1, 1).

The following shows the watchdog timer operation after reset release.

1. The status after reset release is as follows.

•

Operation clock: Low-speed internal oscillation clock

•

Cycle: 2

(546.13 ms: At operation with f

= 480 kHz (MAX.))

•

Counting

starts

2. The following should be set in the watchdog timer mode register (WDTM) by an 8-bit memory manipulation

instruction

Notes 1, 2, 3

•

Operation clock: Any of the following can be selected using bits 3 and 4 (WDCS3 and WDCS4).

Low-speed internal oscillation clock (f

)

Syatem clock (f

)

Watchdog timer operation stopped

•

Cycle: Set using bits 2 to 0 (WDCS2 to WDCS0)

3. After the above procedures are executed, writing ACH to WDTE clears the count to 0, enabling recounting.

Notes 1.

As soon as WDTM is written, the counter of the watchdog timer is cleared.

Set bits 7, 6, and 5 to 0, 1, 1, respectively. Do not set the other values.

At the first write, If the watchdog timer is stopped by setting WDCS4 and WDCS3 to 1 and

respectively, an internal reset signal is not generated even if the following processing is performed.

•

WDTM is written a second time.

•

A 1-bit memory manipulation instruction is executed to WDTE.

•

A value other than ACH is written to WDTE.

Caution In this mode, watchdog timer operation is stopped during HALT/STOP instruction execution.

After HALT/STOP mode is released, counting is started again using the operation clock of the

watchdog timer set before HALT/STOP instruction execution by WDTM. At this time, the counter

is not cleared to 0 but holds its value.

For the watchdog timer operation during STOP mode and HALT mode in each status, see

8.4.3 Watchdog timer

operation in STOP mode

and

8.4.4 Watchdog timer operation in HALT mode

A status transition diagram is shown below.
