The WRST bit in RSTCSR is valid when bits WT/IT and TME are both set to 1 in TCSR.
Figure 11.7 shows the timing of setting of WRST and the internal reset timing. The WRST bit is
set to 1 when TCNT overflows and OVF is set to 1. At the same time an internal reset signal is
generated for the entire H8/3008 chip. This internal reset signal clears OVF to 0, but the WRST bit
remains set to 1. The reset routine must therefore clear the WRST bit.
