4.6.9 Precautions for the H8/36094 Series

(1) The hardware manual says "Initial value = 1. These are reserved bits. When read, they always show the value 1." On
the other hand, the compact emulator stipulates that these bits must always be set to 0, and that when read, these bits
show the set value.

(4) Although the hardware manual describes the functions shown below, they are not available on the compact emulator,
because the evaluation MCU does not have them.
- power-on reset & low-voltage detection circuit
- on-chip oscillator
- The watchdog timer starts operating in the initial state after the reset
- clock output
- Port C
(5) Although the hardware manual says that registers are located at the addresses shown below, the compact emulator
stipulates that writing to the addresses has no effect, and that when read, they show indeterminate values. This is
because no registers exist at these addresses in the compact emulator.
