Notes 1: Either high-speed, middle-speed or low-speed mode is selected by bits 7 and 6 of the CPU mode register.
When low-speed mode is selected, set port Xc switch bit (b4) to “1”.
2: f(XIN)/16 is supplied as the count source to the prescaler 12 at reset. The count source before executing the STP
instruction is supplied as the count source at executing STP instruction.
