11.3.4 RESO Signal Output Timing  
When TCNT overflows in watchdog timer mode, the OVF bit is set to 1 in TCSR. If the RST/NMI  
bit is 1 at this time, an internal reset signal is generated for the entire chip. At the same time a low-  
level signal is output from the RESO pin. The timing is shown in figure 11.6.
