Notes on Use of Boot Mode
1. When the H8/3334YF comes out of reset in boot mode, it measures the low period of the input

At this time, the values of general registers in the CPU are undetermined. Thus these registers

program should be specified.
There are no other changes to the initialized values of other registers.
