Please tell us the port condition when the processor transfers to watch mode without the sub-oscillator being present on the H8/3802, H8/38004 and H8/38024 Groups?
The port maintains the status it had immediately before the transfer for both input and output port. It is not recommended to transfer to the sub-clock type mode without connecting a sub-oscillator. If not connecting any sub-oscillator, be sure to fix X1 pin to GND.
