Section 9 Timers
9.6
9.6.1
The watchdog timer has an 8-bit counter that is incremented by an input clock. If a system
runaway allows the counter value to overflow before being rewritten, the watchdog timer can reset
the chip internally. Note that stabilization times for the H8/38024, H8/38024S, and H8/38024R
Group and for the H8/38124 Group are different.
Features
Features of the watchdog timer are given below.
• Incremented by internal clock source (φ/8192 or φw/32) on the H8/38024, H8/38024S, and
• On the H8/38124 Group, 10 internal clocks (φ/64, φ/128, φ/256, φ/512, φ/1024, φ/2048,
• A reset signal is generated when the counter overflows. The overflow period can be set from 1
• Use of module standby mode enables this module to be placed in standby mode independently
